I saw them in many, many incarnations over the years.

One favorite was a version, after many variations, that included Jon on vocals, both Bill Bruford and Alan White on drums and both Pat Moraz and Rick Wakeman on keyboards.

Another was when the (mostly) classic lineup played at the Hollywood Bowl and basically played just the first 3 albums, with album-length versions of all songs.

The only constant through every incarnation was Chris Squire. RIP Fish.
