Ah, i see someone already brought that up.
Well, for my money, early Collins-era Genesis is still worth seeing. Follow You, Follow me is one of the greatest love songs i've ever heard, Misunderstanding, Abacab, Turn it on Again, That's All, Taking it all too hard... Great stuff. Invisible Touch has its moments, but drifts too far into straight pop, and after that, well, forget it.
