Great thread (though I'm not a Beatles fan) ... demonstrates to me that band-drummers are the lifeblood of many bands ... humble groove masters (oft) that so many bands cannot expel.
As many of you alluded, methinks Ringo grew to assimilate contrary personalities, provided (rapid) timing, unprecocious antics, etc. via years of integration with his fellows. When a youth I felt their tempo was a bit too fast and forced (for the most part) ... so I couldn't really 'sing-along'.
But 'fast-and-forced' tempos were the thing back then. I suppose Ringo invoked that.
I for one wish my band had a faithful decent enthused drummer to grow with. Those of you who have a 'reliable'/caring ... kick-snare-hats ... percussionist seem certainly blessed, IMHO.
