To add to the above, as recently as December I discovered I worked with closet Genesis fans who went to see them, and they were disappointed that there were no Phil Collins songs played.
Also on the topic of phil as the bad guy in Genesis. I firmly believe the guy is almost a genius musically, and as talented as Tony and Mike are, they are not geniuses really. Phil didn't make them a pop monstrosity, but through his ability he enabled Tony's (and to a lesser extent Mike's) ambitions to be a rock star. To some extent he was a translator for their language to the mainstream. None of us can know how music of today will be judged in 400 years time but I'd like to think that if any artist was labeled "misunderstood" it would be Phil. Popular hack? No. Godlike multivalent talent? Yes.
And to finish, I do much prefer the compositional beefiness that Banks/Rutherford added to Genesis than I do Phil solo. I think they are unbelievably good, as evidenced by CAS being in my top 3 Genesis albums and above any Phil solo album. It's just that IT could have been The Fugitive 2 without Phil. Yes, the tour would have been Tuesday night at the Odeon instead of 3 nights at Wembley Stadium!
There are a few bands like that, I think, where the sum of the parts exceeds the individual talents, as they bring the best out of each other. Queen is another, the solo albums all have enormous weak spots (Except Roger's "Happiness?") which display how, for example, Brian's metal excesses get pulled back by the others.
