I've got some friends who run karaoke. Check out IDJProDJ and Red Carpet Entertainment.

I think Sonomas was recently picked back up, and that bar also has trivia.

In Savage, Dive Bar has karaoke multiple times a week. It's a cute bar, and always a good time. Tommy, the guy that runs it, is hilarious.

His partner, Thiery, runs Odies, State Fare in Catonsville, and a few others as well.

The Catonsville run is the most popular. El Guapo, State Fare and I think there's one more.

Any and all of these will have nights like you're looking for, a.d the people you'll meet will be friends for years.
