I know that when you're opening for a well-known act with songs they've written and/or made famous, it's a flat-out no-no to play those songs as part of your own setlist. In fact a BL I know basically got his band blackballed with a certain local promoter for doing exactly that. But what if all the bands on the bill (including the headliner) are nothing more than "weekend warrior" cover bands? I'm in a cover band and a few times this summer we've headlined multi-band bills. The first act(s) get anywhere from an hour to 90 minutes each and then we go on around 9:30 or 10 and finish out the night with a ~3 hour show. Anyway, on a couple of these gigs the bands ahead of us played songs that we also do in our show. In almost every case the opening bands played those tunes so badly (or at least, so differently than our version) that the audience may not have even recognized it but it still felt kind of weird. So I'm looking for thoughts on the following: 1) Do different rules apply when all the bands are playing mostly or exclusively covers? I mean, it does seem a little ironic/hypocritical for one band to jump another band about playing a song that isn't "theirs" to begin with. 2) Since I anticipate we'll be doing more shows like this in the future, are we in-bounds as the "headliner" to ask to see the other bands' setlists in advance and request they not play certain songs if they're the same ones we do? Or would that be a totally douchey thing to do? Thanks in advance.
