For a limited time, May 31-June 28, admission to the late shows Saturday is $20 per seat. The 10 PM Saturday performance at the John Houseman Theatre takes the place of dropped 2 PM Saturday shows starting May 31. Later this summer, tickets for the late show go back to a top of $65. The other Saturday performance plays 7 PM rather than 8 PM.

The deep discount is to lure young club-going audiences who may want to start their evening off with the pop friendly musical, a spokesman said. The move is expected to help word of mouth for an already hot-selling title that has had crowds cheering since a test run Off-Off-Broadway in fall 2002.

The new Off-Broadway staging of the musical by newcomers Tim Acito and Alexander Dinelaris earned solid reviews, awards nominations and will have a cast album from PS Classics this summer.

The cast includes Jai Rodriguez (as Zanna), Anika Larsen (as Roberta), Darius Nichols (as Buck), Amanda Ryan Paige (as Candy/Karla), Enrico Rodriguez (as Mike), Robb Sapp (as Tank), Shelley Thomas (as Kate) and Jared Zeus (as Steve). Most of the players double and triple in roles. The intermissionless show began previews March 5.

Jack M. Dalgleish and Stephanie A. Joel produce. Devanand Janki directs and choreographs. He snagged a 2003 Lucille Lortel Award for Outstanding Choreography for Zanna. Musical supervision is by Edward G. Robinson. Production designers are Wade Laboissonniere and Tobin Ost. Lighting design is by Jeff Nellis and sound design is by Robert Killenberger. David Geist is musical director and dance arranger.

Other nights, tickets range $55-$65. The John Houseman is at 450 W. 42nd Street. For information, call (212) 239-6200.
