Zappa Plays Zappa Setlist at Shepherd's Bush Empire, London, England

I know adding @Song[Frank Zappa] seems redundant, but it's necessary to keep the song and album statistics correct. We have discussed hiding the @Song tag for related artists like Zappa Plays Zappa. This could be implemented in the future.

For the record the 'Frank Zappa cover' note is not correct for the following tracks:
'Montana' is a "Frank Zappa & The Mothers" cover.
'Village of the Sun' is a "Frank Zappa & The Mothers" cover.
'Echidna's Arf (Of You)' is a "Frank Zappa & The Mothers" cover.
'Don't You Ever Wash That Thing?'is a "Frank Zappa & The Mothers" cover.
'Inca Roads' is a "Frank Zappa & The Mothers Of Invention" cover.
'Carolina Hard-Core Ecstasy' is a "Frank Zappa & Captain Beefheart" cover.
'Son of Orange County' is a "Frank Zappa & The Mothers" cover.
'More Trouble Every Day' is a "Frank Zappa & The Mothers" cover.
'Zomby Woof' is a "Frank Zappa & The Mothers" cover.
'Willie the Pimp' is "The Mothers" cover.

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 10 songs you mentioned, since there are likely other songs in the same situation.
