Some time ago I mentioned that I was puzzled as to why/how I had a GTR record. This morning it occurred to me that it's because GTR is part of the "extended Yes family" via lead singer/guitarist Steve Howe.
So that's at least four groups that I know of: Yes, Buggles, Asia and GTR. Are there any others? Not counting solo artists, just groups (or duos, two or more anyway).
I finally filed my tax return this morning.
