Trespass is a great album, and it was the album before Collins and Hackett joined. I also have some of the Ant Phillips solo albums, Phil even sang on a couple of songs.
“The Geese & The Ghost” was well-worn on my turntable at the time.
btw - saw “Musical Box” (tribute band) do the Lamb Lies down on Broadway album. Genesis sold them all the props, videos, etc. A worthy effort.
