Houston's next for the traveling Sing-Along Sound of Music. The campy interactive showing of the famed Julie Andrews movie plays the River Oaks Theatre Feb. 22-March 14.

A sell-out success at London's Prince Charles Cinema and in a tour throughout Britain, this special "Sound of Music" gives audiences the chance to do what they've always wanted to do during the sugary-sweet Julie Andrews flick: dress up as nuns, wave edelweiss and sing along to the Rogers and Hammerstein tunes to the rhythm of the bouncing ball. Attendees are encouraged to dress the part for the "Sing-a-Long Sound of Music." Any costume, aside from those nasty Nazis, is welcome, and they have ranged from the usual (the Von Trapp children in their curtains) to the bizarre (goats — with and without Lonely Goatherds — to a young man in a gold lycra catsuit (give up? He's Ray, a Drop of Golden Sun)).

An interactive pack accompanies the movie (a plastic nun is among the goodies) with host leading a vocal warm up, introducing a comprehensive list of shouted comments and gestures (a la "Rocky Horror") and judging the costume contest. Winners will receive 35th anniversary DVDs or VHSs of "The Sound of Music."

Tickets are $20-$22.50. For reservations, call (281) 397-8124. The River Oaks Theatre is on the web at http://www.landmarktheatres.com/Market/Houston/RiverOaksTheatre.htm.
