Open Mic nights/Karaoke places Nashville, not at bars?

My band (My Anthem) and I have decided that we should try and sing at
an open mic night, kraoke place, or something. Are there any places in
the Nashville Tenn. area that aren't at bars? They need to be safe for
teens/kids from 10 to 14 and not too late at night. The lead singer's
sister is 17-18. We play alternative pop, rock, punk, and
non-swearings (the worst thing we have is "feelin' kinda ditzy, after
falling for the fake charm, that you gave me" and we're going to cut
"don't be a douche, just tell the truth, you know she fell for you,
now that's it, tell me the truth so I can leave before eveyone else
falls for you too" from "You know (I fell for it too)")
