For the third year, Mr. Richard and the Pound Hounds will return to Orlando Repertory Theatre for an interactive Halloween concert. Mr. Richard, who specializes in rock music for kids, created this concert especially for the Rep. It features sing-along tunes about critters such as fish, skunks and snakes, as well as Halloween fun. Youngsters are encouraged to wear their costumes to try them out before the trick-or-treating later that night. The concert will be at 1 p.m. Saturday, Oct. 31, at Orlando Repertory Theatre, 1001 E. Princeton St., Orlando. Tickets are $10. Call 407-896-7365 or go to orlandorep.com.
