Zappa Plays Zappa Setlist at Barbican Centre, London, England

Incomplete, I've entered all the songs I can remember; hopefully somebody else can alter/complete. What a fantastic show!

They also played "I'm The Slime" but I can't say exactly where, somewhere between "City of Tiny Lights" and "Fifty-Fifty". Brilliant show!

'I'm The Slime' was the first encore song. I thought they might drop 'Dancin' Fool' or 'Muffin Man' as soon as I heard it, but thankfully they didn't.

I am sure there was at lease a trace of Chunga's Revenge during/after Inca Roads....however great concert

Added "I'm the Slime" - first encore

Although all of the songs are listed as 'Frank Zappa covers' this is technically incorrect.
'What's the Ugliest Part of Your Body?' was recorded by "The Mothers of Invention". 'Montana', 'Inca Roads', 'Cheepnis', 'Fifty-Fifty' and 'I'm The Slime' were all recorded by "Frank Zappa & The Mothers". 'Muffin Man' first appeared on an album by "Frank Zappa & Captain Beefheart".
As most, if not all, of the ZPZ setlists on Setlistfm (100+) are also technically incorrect in this respect, I dare not make any changes to this one lest the mods ask me to change all of the others too!
What to do?

If you want to go through all the songs by FZ and ZPZ and tell me which songs were released by whom, I'd be glad to update them. I'm not familiar enough with Zappa's discography to do it myself. And I don't want to update only the 7 songs you mentioned, since there are likely other songs in the same situation.

@ leglessmoof: It was only an observation, and I regret that I don't have the time for such a task.

HI ---

Think there may be a slight confusion in the setlist -- rather than "Cheepnis" the Roxy & Elsewhere stuff was "Echidna's Arf" segueing into "Don't You Ever Wash That Thing?" (with the "watch Ruth" adapted to Billy H) --- can't remember where it was in the setlist --- perhaps where "Cheepnis" is currently sitting or perhaps earlier?

Also, a nice and sleazy "Bamboozled By Love" was in there, but I can't remember when.
