I love Ringo's playing. As has been mentioned on the forum before, the composition of his drum parts is inspired and a lot of stuff he plays is harder than it sounds to get vibing the way he does.
Was it George Martin who came up with the parts? Maybe at times but I'm sure R came up with plenty himself because there are some fine drum parts on his solo stuff too. How about Instant Amnesia
from his Ringorama album?
Love it love it love it!
