Interestingly he insinuates at one moment that Steve wasn't getting as much songwriting credits in the band cus his songs just weren't as good as Tony and Mike's.
And that while he and Peter shared no ill will against each other (no surprise, since they collaborated so much in the late 70s), Peter and Tony's relationship was strained by the split. Phil doesn't elaborate though (give me that autobio tony!)
Apparently in 1979 Phil played solo shows with Peter for a short while, even singing lead vocals together for some songs, I didn't know that before.
I liked a bit where phil talked about how it was Bruford who initially asked to play drums for Genesis for the Trick tour and Phil tried to dissuade him by saying they were too much like Yes for him.
Also amusing was a story from right before Phil joined Genesis where he got an out-of-nowhere invitation to play percussion on All Things Must Pass. Then when he heard the record he discovered he didn't make the cut, and he wondered for years why and George Harrison claimed to not remember him at the session. Then like 30 years later Harrison sent him a tape of "Art of Dying" with shitty awkward percussion all over it, and Collins realised he just sucked at the time. But then it turned out that Harrison was fukcing with him and he just couldn't actually find the tapes with Collins on them.
