And little Early Birdie gave my anus curl a whirlie and asked me if I needed a ride

The story:

No, this isn't yet another submission about "wrapped up like a deuce," though I always misheard that one too. The "Early-Pearly" line was one I misheard in an even more disturbing way.

To a certain extent I knew it had to be wrong because of how I misheard it, but no amount of straining to listen enabled me to figure out what he was really singing. But I had these disturbing visions of a human-sized bird taking a talon and twirling it in the hair around Manfred Mann's butt crack and then carrying him along for a ride. And I still haven't exorcised those thoughts.
