The INDYPROV vs. ComedySportz Karaoke Smackdown is a new event slated to take place every other month to raise money for local charities. This month, the proceeds will benefit Theatre on the Square. Both troupes will play unique improv games as they sing karaoke at The Mass Ave Pub, 745 Mass Ave., Aug. 10 beginning at 9 p.m. The crowd votes for their favorite by putting money in the appropriate troupe's bucket.
