On Dec. 1, Los Angeles will experience the fallout of what happens "When Casts Collide."

As reported by the Los Angeles Times, "Collide" is a special benefit for AIDS charities on World AIDS Day. Malcolm Gets, of TV's "Caroline In The City," will host the event, which unites cast-members of three L.A. companies. Alyson Reed, on Broadway in Marilyn and the last revival of Cabaret, directs.

Appearing in the show, scripted by Faye Greenberg, will be ensemble members of the musicals, Ragtime, Rent and Phantom Of The Opera. Show tunes will be sung; however, according to spokesperson Tim Choy, the songs won't be from those three musicals. Instead, they'll be Broadway melodies from the eras represented by the shows. For example, Rent will stick with the rock era, Ragtime will choose tunes from the early 20th Century.

For tickets ($35-$250) and information on "When Casts Collide," billed as "a musical celebration of life, love and hope," call Telecharge (800) 233 3123. The $250 tickets come with a post-performance party. Charities benefiting from the event include Project Angel Food, BC/EFA, H.E.A.L. And the Serra Project.
