Sat. Jan. 27

The Regent Theatre in Arlington is one of those old-school venues some of treasure more and more of nowadays. It was built in 1916 and is in need of a production equipment upgrade - certainly, not its first since pre-WWI, mind you, but one that's needed to keep up. Some of the acts that have played the Regent - the Ultrasonic Rock Orchestra (in photo), Ben Rudnick's Johnny and the Moondogs, juggler Dan Foley (of the Airborne Comedians) and members of the Legacy Dancers and faculty of the Dance Inn in Lexington - are staging a vaudeville-like benefit show for Saturday Jan. 27 at 8 p.m. True diversity. For us, the main attraction is rock opera from Sal Clemente and his URO buddies. We saw them rock the bejeesus out of "We Will Rock You" and other rock opera-esque songs a while back. You know, the Who, Bowie, Queen. Big chords and big themes. Then, there's the Moondogs acoustic-electric new and old rock, comedy and juggling from Foley and young dancers (ages 10 to 18) and their teachers doing tap, jazz and more. Fun for the whole darn family. Tickets: $30-$15.
