His style is commonplace now but was unique when the Beatles came out. Like much of the Beatles' music has become commonplace and contemporary... All of the copycats that came after made it so...
I'm not huge into drums but what I'm talking about when I say Starr's drumming style (especially in like 64-66) is his gratuitous use of cymbals and snares in comparison to a lot of drummers that seem to use a lot more (or at least put more emphasis in) the toms (I think that's what you call the drums without snares in them?

) and bass drum.
ex. of what I'm talking about (Roll over Beethoven)... In my opinion at least, the initial thought at the guitar intro is that 'oh it's a British band covering Chuck Berry'... and then Ringo comes in and it's 'Oh the Beatles are covering Chuck Berry'. There are a lot of songs like this from that period but this is the first one I found from youtube that was of decent enough quality that you can hear it well....
