Saw them on the ...and Then There Were Three... (Glasgow Apollo) and Abacab (Ingleston) tours - first was better probly because the Apollo was a proper theatre. The band played Musical Box (Glasgow) & Suppers Ready (Ingleston) as well as Cinema Show, Firth of Fifth and I Know What I Like... at both shows, so quite a bit of Gabrial era stuff.
Listening to the 2007 reunion tour it was noticeable to me how much more of a "singer" Collins had become which I felt detracted from their best work - up to the 1984 Genesis elpee.
