Except for YMCA (which luckily I have not played in years.. sorry that is a nasty piece of business there

), your list is a pretty good one. Great basslines and people dig 'em on the dance gigs. Haven't done Disco Inferno in years, but the others seem to pop up every once in a while with the various bands I play/sub with.
Every once in a while during a breakdown or whatever, one of the singers I work with does 'Freak Out', which is also a fun and challenging bass line. Anything by Chic still sounds fresh and interesting to me.
