In July [1971], The Music Press Gave Reports Of The Many People George Was Assembling For The Concert.

In July [1971], the music press gave reports of the many people George was assembling for the concert. It was rumoured that his friend Dylan might even turn up, but Terry [Doran] told me George was having slight problems with Bob. Dylan had not performed for quite a while. Now George was asking him to make his 'comeback' in the hardest of all performing situations: at Madison Square Gardens with a bunch of musicians he had never played with before. One day during rehearsals, Dylan apparently got uptight and said he just couldn't do it; he was too nervous. George went wild: "You're nervous! What, are you crazy? I've never performed without the other three. At least you're used to performing on your own!" Dylan then explained that the concert was becoming a hassle. Again, George went wild. "I'm the one trying to put it together. All you have to do is sing!" Dylan walked out of the rehearsals. (He was not seen again by George, or anyone else, until the night of the concert. George didn't know if he was coming or not. So when the time allotted for Dylan came in the concert, live and on stage, George looked into the stage wings. There was Dylan, ready to come on. George still didn't know he was going to perform until Dylan started to stroll on stage. Dylan was a major hit, possibly the limelight of the show. It did Dylan good, too. He had regained his confidence and returned to the road for a tour shortly after the concert.)
