John wasn't too fond of George's religious stuff....he does a "Blow Away" parody of sorts called "The Happy Rishikesh Song" on the Anthology boxed set.......John was never on any of George's recordings, I believe.....which seems to make sense, as at least George could play the guitar on John's songs. What could John do on a song that George had written?
Btw, George actually wanted to start a band with John in the 70's. True story.
