I have been waiting all year for the 94.9 MIXfm Christmas Radio Play, “Merry Twistmas, Tucson." The annual live performance and recording is Sunday at 5 p.m. at the Fox Tucson Theatre, 17 W. Congress St.

The story is an original play written by the Star's David Fitzsimons. 

Visits from alien spacecraft, martians and a festive Chupacabra mark the journey of main characters Marge and Tom as they vie to win first place in the Winterhaven Festival of Lights Decorating Contest and ultimately understand the true meaning of Christmas. This musical extravaganza promises to keep everyone from tots to seniors on the edge of their seats and tapping their feet.

The cast includes Mayor Jonathan Rothschild, Police Chief Chief Villaseñor, TV news anchors (I hope KGUN 9's Guy Atchley reprises his Keebler elf performance) and various MIXfm DJs. I'm going to play Detective Alvarez! The score and effects will be provided by Diane Van Deurzen and Lisa Otey. 

This is also a benefit for the Diaper Bank of Southern Arizona. The DBSA distributes half a million diapers annually to those in need across the local community. Babies aren't the only ones that need the donations. 25 percent of the donated diapers go toward adults with incontinence needs.

General admission tickets are $15. Special VIP events: VIP floor seating and reception with cast, $50; VIP love-seat seating for two and reception with cast — $100.
