Weezer are playing a very-sold out show tonight at the Sinclair in Cambridge, and have sent out a call for female fans to join them onstage to be part of a backing choir. The only catch is that you need to already have a ticket to the show.

And since the very-in-demand $65 tickets to this “club gig” are non- transferable — as one Craigslister famously found out the hard way — chances are the ladies who will join Weezer tonight will have had to pay for the privilege.

The help wanted ad reads: “Attention Bostonian Weezer fans! We still need 4 more female fans who already have tickets to the Sinclair show to join the Weezer choir. If you are a strong female singer and want to join Weezer onstage tomorrow night, please email weezermusicdirector@gmail.com ASAP!”

Earlier posts to the band’s Facebook page, which was seeking similar contributors for shows in Philadelphia, New York City, Pomona and Los Angeles, asked the following questions: “1. What vocal part do you sing? (Soprano, Alto, Tenor, or Bass) 2. Can you read music? (Not required, but helpful!)”

Didn’t Amanda Palmer get a bunch of shit for this sort of thing a while back?

Weezer’s new album, Everything Will Be Alright In The End, is out now via Republic.
