Amusingly he discusses that whenever the five of them have gotten back together for some meeting or event they immediately revert to their old roles in the band with Peter in charge, Tony fighting him for leadership, Mike as the mediator between them, Steve as the quiet one, and Phil as the jovial guy who defuses the tension during disagreements and happy to go along with whatever the other guys want.
He doesn't have that high of an opinion of all of his solo albums. He unsurprisingly thinks his debut is great and really likes Going Back, but he considers his best solo album to be Both Sides (never heard it so I can't comment). His other solo albums he mostly talks about as a place for his solo songwriting when Genesis decided to only put collaborative songs on their albums. He's mostly neutral about them aside from a couple of highlights he likes on each. He doesn't really have anything positive to say about Dance Into The Light and Testify aside from that he enjoyed making them. He likes his Tarzan songs and considers working with Disney on that film to have been one of the biggest honours in his life.
Mostly he talks about his songwriting as an outlet for him to vent about his continually screwed up personal life and is surprised that it's so massively successful. He talks about how he was such a workaholic throughout his whole life that he didn't realise just how inescapable he was in the 80s and 90s (and that many people resented him for that) until looking back after it was all over.
