Also, what about experimental songs like Tomorrow Never Knows
? The drum part - though powerful and tight - is very limited and repetitive, which IMO is exactly what the song needs for that locked-into-a-groove droney feel.
A drummer such as Keith Moon wouldn't have done that, I feel. He'd have been all over the kit in that flashy way of his - and don't get me wrong, I LOVE Moon's drumming. The man was a drummy god.
So yes, Ringo was limited in some areas. But he shone in others.
BTW - I LOVE the drumming on Rain
and She Said, She Said
. '66 was a good year for Ringo.
