Watcher is right - the key is what the encore(s), or rather, second half, would be.
For me, Can Utility and the Coastliners, Watcher of the Skies, The Fountain of Salmacis and, most importantly, Supper's Ready.
FOXTROT!!!!!!!!! Concert classics Watcher Of The Skies and Supper's Ready!!! The short-lived live number Can-Utility and The Coastliners!!!! The never played live Time Table!!!! Get 'Em Out By Friday and Horizons!!!!
OR
NURSERY CRYME!!!!!!! Early live classics The Musical Box,Return Of The Giant Hogweed and The Fountain Of Salmacis!!
The barely played live Seven Stones,Harold The Barrel and Harlequin!!!!! The never played live For Absent Friends!!!
Either one of those albums would be fine with me!!!! The edge might go to Nursery Cryme for the amount of rarely played live tracks.The Lamb has been done plenty of times. I would also like to see them just play with no costumes or theatrics. Just them,the stage and the music with a killer light show at the very least in a small theater. Of course,if the reunion does happen and they play the Lamb with a full blown stage show at Madison Square Garden, I'll be the first one on line sleeping on the sidewalk for a week!!!! YOU GOT THAT RIGHT!
