Based on a discussion at work, which Beatle produced the best work in a band post-Beatles era. John Lennon really didn't have a band per-se, but he made music with Yoko, so that's close enough. I'll argue that the Traveling Wilbury's produced the best music, and I can listen to those two albums on a regular basis without getting tired of them. Plus, just an amazing line up!
All pretty good bands, but I voted for the Travelling Wilburys. More my era. I would give ELO an honorable mention, since they continued the Beatles baroque-ness in their music, at least early on. More Beatle-esque in a way than any of the solo members.
Definitely the Traveling Wilburys even if they only did two albums and only one of them with the full line-up. Because they were a wide range of incredible talent, they produced some wonderful classics like "End of the Line," "Handle Me with Care," "Not Alone Any More," "Margarita," and a personal favorite, "Wilbury Twist," which is just so much damn fun. I only know handful of Wings songs, but what I've heard, I've enjoyed although not on the same level as the Traveling Wilburys.
Wings were actually pretty decent, and Wings Over America is a great live album that I would recommend to everyone. My main issue is that Paul has too many of the 'Silly Love Songs' peppered throughout his work, and Harrison has very little (Got My Mind Set On You being a glaring exception).
I didn't think much of Wings and thought the Wilburys were crappy despite Tom Petty being involved. Ringo's stuff was at best workmanlike. John and Yoko were terrible. John without Yoko however, produced some fine work.
I really like a handful of Wings' songs, but I gotta go Wilburys too. ...Well it's all right, doing the best you can.
Not counting solo work? Wilburys. Though I prefer Lennon’s first two solo albums. Paul’s solo work can be a bit bouncy and saccharine.
Shouldn't Lennon's band be The Plastic Ono Band? Several of his solo albums are credited to various incarnations and permutations of that group. Though interestingly enough not Imagine.
I had to go with PM & Wings. I legitimately don't like a single thing that Harrison, starr and Lennon did after the Beatles, but I like several post-Beatles McCartney songs.
Probably the Traveling Wilburys, though it’s a little unfair to compare a supergroup like that with the band Paul put together in the immediate aftermath of the Beatles. For my money, Band on the Run is as good a song as Paul wrote in the Beatles, but my favourite post-Beatles work by any of them is George’s All Things Must Pass album.
The Dirty Mac gets my vote -- Lennon, Eric Clapton, Keith Richards, and Mitch Mitchell, plus Ono and Ivry Gitlis. I kid, I kid. The Dirty Mac was a one-off performance in 1968, before the Beatles broke up, but their performance of "Yer Blues" was superior to the version on the White Album. For a serious answer: 1) The Traveling Wilburys 2) Paul's current touring band (2001-present, has been called "the world's greatest Beatles cover band") 3) The Firemen 4) Plastic Ono Band ("Lost Weekend" era, with Jesse Edd Davis) 5) Ringo's All-Star line-up (2012-2016) 6) Plastic Ono Band 1969 configurations (Lennon, Clapton, Klaus Voormann, Alan White/Ringo Starr) 7) The Roundheads (Ringo's studio album band, 1997-2008) After that would be various Wings configurations, All-Star Band configurations, and Plastic Ono Band configurations. The worst would be Band Aid 20 (Paul played bass on the backing track).
Another Wilbury vote here. I really enjoy the cover of Del Shannon's "Runaway" ( a bit of serendipity there ). Just a solid group of pros. (Big ELO fan, too.) Lynne produced the final two Beatles songs, after all. Wings Over America is hands down just an awesome album. "Maybe I'm Amazed" was supposed to and should have been a Beatles song. But if I had to go best song from the solo Fab Four: "Imagine" by a country marathon!
George's stuff was probably the most listenable, but kinda cheated by getting into another super-group. Maybe there's an earlier example, but doesn't this sort of start that whole thing? Bored musicians getting together with other friends from big bands and making the super group? George also had some decent solo stuff. Probably the most even result out of the 4, solid music that fit the mellow 70's thing that was going on. Paul had the most longevity/success probably, but was too soft/sappy/commercial. Which was always kinda his thing; he needed John to give him an edge and push him out of the tendency to write cute jingles. He was never going to go hungry, though, he's got too much talent and knows what sells. Ringo's stuff was... well, Ringo has to eat too, so can't fault him. Couple decent things in there, but meh overall. If he wasn't a Beatle, none of that probably stands on its own. John's stuff was the most out there. Right in line with his Beatles contribution. Didn't play it safe, and solo he didn't have Paul to soften his edges. So that resulted in a lot of experimental stuff, mostly garbage. But also some great stuff, and Imagine was probably the biggest/most important contribution out of anything any of them did. War is Over, Instant Karma, he had some good stuff in there. But also stuff with just screaming. had the crazy to go with the extreme talent.
John and Paul had stopped writing together long before the band broke up, so their influence on one another in terms of their songwriting, was practically nonexistent long before the two went solo. The "experimental" stuff after the break up was likely more Yoko's influence than anyone else. His solo career was, IMO, less "edgy" and more what I'd call, "basic". He wanted to get away from the progressive rock associated with the Beatles and get back to basic Chuck Berry, Larry Williams, Arthur Alexander type rock, thus the overabundance of that annoying echo affect on so many of Lennon's post Beatles records. I thought George was the best writer in the Beatles toward the end. He, along with Paul, wrote the best post Beatles' songs. Paul wrote some really good post Beatles songs, he just never wrote another Yesterday, or For No One, or Got To Get You Into My Life, Eleanor Rigby, etc.
