Jillians' 11-piece Party On the Moon band has enough impersonators to recreate everybody from Bob Marley to MC Hammer to Frank Sinatra. Nothing is sacred--from the all hat and no cattle new country boys to the old warhorse David Allen Coe, who still wonders why you don't call him by his name. If that ain't your bag, hold on a minute--Smash Mouth, ZZ Top, Wild Cherry, Santana and Aretha Franklin follow one another in the most unlikely lineup this side of sanity. Lynyrd Skynyrd rubs elbows with Joan Jett, Eric Clapton and the Eurythmics and unlike the reality version of that lineup, nobody gets hurt. Outside your record collection, it's the only way you'll ever get all these people under one roof--and you won't have to mortgage your soul to see 'em. Second Hand Flapjacks open. 7 p.m.-2 a.m. $15-$55. 821-7887.
