Nice that you're adding Zappa's sets. But can you give the source under setlists?
PS Maybe you don't know this site: http://www.zappateers.com/fzshows/6669.html
I don't speak english but
The source is here:
About Frank Zappa
Can you fix the relation Songs/Albums?
It's completely wrong.
I don't know if I spoke correctly, but I think you understand... (using Google Translator...)
Unfortunately, I can't change them now as something is broken. But I will do it as soon as it will be fixed.
