If you live in Britain or Ireland,keep your eyes peeled for the Sky Arts channel listings-this show has already been shown on that channel and you can record it on Sky Plus.
Some has been released on YCDTOSA Vol 1 and "As An Am" on the Beat The Boots series,and some of the show not on this release turns up on the "Dub Room Special" DVD.
It's a fair-to-middling 1981 band,pleasant enough but not outstanding.If you're a Zappaphile,you probably have already heard most of this show in legal or unofficial recordings,so it can't really be recommended that much.If you're new to FZ,try "Dub Room Special" mentioned above.
Where's the DVD of the 1973 Roxy shows? Gail Zappa says "Look out on You Tube".No official release yet-bugger!!
