Good man! They're my favorite group as well. I've been a fan since the early 1970s and have been lucky enough to meet or exchange e-mails with more than a dozen of the Comets over the years, as well as Bill's daughter Gina Haley.
From the above clip, you might be interested to know the guitar player, Franny Beecher, is still alive and well and performing regular gigs in Pennsylvania after retiring from touring with the Comets only 3 years ago. The original members of the Comets (not the gentlemen seen in this clip - there was a changeover in membership a few months before the movie was made in which Haley's sax player, bass player and drummer left to form their own group, the Jodimars, only to reunite as the Comets in the late 1980s) were still touring and performing as recently as December. Last I heard they were planning a European tour next spring. The bass player in the R-O-C-K clip, Al Rex, is also still alive though last I'd heard he had retired from performing.
Here are some clips of the original lineup performing in the ultra-rare, very FIRST rock and roll movie of all time, 1954's RoundUp of Rhythm. Note that they did not have a lead guitar player at this point:

(Not sure why there's a picture of Elvis at the end of this one - probably part of a documentary)

Straight Jacket - with Bill Haley playing lead guitar, the only known footage of him playing an actual guitar solo (other than miming to a recording):

When Marshall Lytle (bass), Dick Richards (drums) and Joey Ambrose (sax) left the brand, Haley's new sax player, Rudy Pompilli, composed a new signature instrumental called Rudy's Rock which incorporated the antics from Straight Jacket:

Wonderful stuff! I was talking to a professional drummer who tried to replicate Ralph Jones' drum solo from this performance, and he said it is much harder than it looks!
