The quality of the food varies, and the shows range from hilariously creative to the occasional damp squib. But over its 25 years, Heritage Square Music Hall has always been worth a visit. The melodramas and songfests feel like a wonderful party where your friends get up, one by one, to tell jokes or sing songs — though your friends aren't likely to be as talented as director T. J Mullin, who maintains a soft-spoken dignity on stage, right up until the moment he turns into a wailing baby; Rory Pierce, who'll play it straight for a while and then pop up in drag, showing off the best legs in the business; Alex Crawford, a grandfather who can still do the splits; Randy Johnson, who pounds the piano keys with such skill and enthusiasm that you have to sing along. And where will we go after December 31 — when the place closes — to see Annie Dwyer, the crazed comedian who made her mark snatching glasses of booze from customers' tables and downing them, impersonating singers from Janis Joplin to a fat-suited Mama Cass, terrorizing male audience members with sticky red forehead kisses and then yelling at their female companions? There is still a season's worth of shows to see, but the fun will stop at the end of the year, with Merry Christmas to All and to All a Good Night.
