Two Pianos, Four Hands isn't the only 88-keyed musical reaching Manhattan. Move It And It's Yours, a musical developed at Blackjacks V (the fifth annual festival of new works-in-progress sponsored in late January by NY's Collaborative Arts Project 21), gets a further workshop by CAP 21 March 5-8.

Move It And It's Yours, has this odd premise: a man forced to move his baby grand piano out of his upper west side NY apartment encounters all sorts of neighbors with different designs on the instrument. Susan Rosenstock directs this musical comedy by Bill Weeden, David Finkel and Sally Fay. Appearing in the workshop are Jed Abrahams, Julie Beckham, Billy Kay, Jeffrey Landman, Amy Wolk, Mark Sheremeta, Jennifer McGill and Matty Stuart.

The idea of Collaborative Arts Project 21 is to give composers, librettists, playwrights and screenwriters a place to stage-read their new works. Frank Ventura serves as artistic director.

For tickets ($10) to Move It & It's Yours at CAP 21's studio, 18 West 18th St., call (212) 807-0202.
