I can think of a couple of things you could do. Here's one.
Find a very large, tattooed, cigar-smoking female body builder/wrestler, pay her to come to the club as your new girlfriend (who you've also reserved a front row table for, and make sure everyone in the club knows she is your 'new' flame). Try to control your gag reflexes as you give her a big juicy kiss just before starting the set. Give her a bonus if her presense causes a confrontation that results in bodily injury to the banshee. Two nights should do it, which is a small price to pay. Let me know how it works out smile.
