I think there was a thread like this on another, long-ago message board; but I'd like to start a new one.
What Genesis songs can you think of that (intentionally or not) happen to have other songs' titles in their lyrics?
Here's what I know of off the top:
The Magic Of Time: Silent Sun
Supper's Ready: Like It Or Not
Firth Of Fifth: Shepherd
The Lamia: Silent Sorrow In Empty Boats
A Trick Of The Tail: That's All
Alone Tonight: Tonight, Tonight, Tonight
Tonight, Tonight, Tonight: In Too Deep
