Lennon wrote "monkey". If i remember correctly, he wrote it while they were hanging out with the maharishi and some of the lyrics were taken directly from things the maharishi said. Paul might play drums on it though. I think that was one of the songs they recorded during the period when ringo "quit". I'm not 100% sure about that one so don't jump down my throat if i'm wrong.
I'm not jumping down your throat. This stuff is important, though.
Lennon wrote it.
Ringo drums.
It was maharishi influenced. "Let's go, c'mon, it's a joy!" (let's meditate).
Recorded while rehearsing. The tape was recorded slow to sound faster on playback.
Killer bass part, too.
I like the ice bell, or whatever it is. DINGA DINGA DINGA...crazy...
