Ringo's drumming was NOT ''bad''
He wasn't the greatest ever, but by far NOT anywhere near the worst. He wasn't meant to be the stand-out star (pun intended) but to hold the beat/band together in the background.
George Martin, familiar with drummers, gave him a pass.
Jealous people can't stand that he got a huge break - like Pete best girly fans.
