If I remember correctly, he picked
- Dance On A Volcano
- Firth Of Fifth
- Supper's Ready
- Dancing With The Moonlit Knight
- Squonk
- The Lamb Lies Down On Broadway
- Fly On A Windshield
Not sure if there were more..
So no real surprise here, basically just the classics
He said he doesn't dislike the later stuff by them, but they did not influence him the way the early stuff did. Also he mentioned, sometimes he finds himself writing a song and realizing that this had already been done by Genesis. And sometimes he finds himself realizing that HE had already written something similar. So, interesting comments apart from the actual list.
