Carpet Crawlers, Cage, IKWIL, the snippets of Moonlit and Slippermen (then at some shows NYC and The Knife). More than 2 but I never thought about how few there were. It was my first Genesis tour and I was just excited to be there, didn't really bother too much about which eras were represented. Admittedly I had hoped my first Genesis shows would come with the lavish presentation I'd heard about so was a teeny bit disappointed, but it showed that even with the basic lights they could still make it visually distinctive, more so than most other bands of the time.
I really liked the Encore set and yes, with their ubiquitousness today it's somewhat lost how mindblowing it was to see lights change colour and move. It was smart to keep the varilites stationary for the first few songs so that when at that "must die...." moment in Dodo a whole bank of them swept inwards, it was quite stunning.
I've got just over 48 hours until my first show and regardless of the set I will enjoy it. I've mainly managed to avoid setlist spoilers and you didn't mention specific songs so your comment here is in a weird sort of demilitarized zone! It gives me a flavour of the set without actual song spoilers. Oh well. I said I'd avoid this board completely once the tour started but haven't so it's mainly my own fault that my unawareness has been chipped away at!
That was the UK setlist. In North America, we got the intro of Dancing with the moonlight knight which went straight into Squonk. And no knife; again, a UK song only.
