The appearance celebrates the recent release of the Broadway cast album, on the PS Classics label.

All nine troupers, including the musical's acclaimed stars, Tony Award winner Christine Ebersole and Tony Award nominee Mary Louise Wilson, will attend.

The appearance will last until 6:45 PM, prior to that evening's performance at the Water Kerr Theatre.

Times Square Virgin Megastore is located at 1540 Broadway between 45th and 46th Streets.

At the signing, cast members will autograph Grey Gardens CDs only. Those attending the event may bring copies of the CD they've already purchased, or they can purchase them on site. The Broadway cast recording of Grey Gardens was released March 27 on PS Classics. Recorded Feb. 13, the album is produced by multiple Grammy winner Steven Epstein (The Light in the Piazza).

The new disc replaces the previously-available world premiere recording, which was also released by the Grammy-nominated label. That recording featured the Off-Broadway cast, based on the musical's original run last year at Playwrights Horizons.

Joining Ebersole and Wilson in the cast are five-time Tony Award nominee John McMartin (Follies, Show Boat, Into the Woods) as both Major Bouvier and Norman Vincent Peale; Matt Cavenaugh (Urban Cowboy, national tour of Thoroughly Modern Millie, "As the World Turns") as both Joe Kennedy, Jr. and Jerry; Erin Davie as Young "Little" Edie Beale (the national tours of Swing! and The Music of Andrew Lloyd Webber); Kelsey Fowler as Lee Bouvier (in her Broadway debut); Sarah Hyland (title role in Paper Mill's Annie) as Jacqueline Bouvier; Obie Award winner Michael Potts (Lennon) as Brooks Sr. and Brooks Jr.; and two-time Tony Award nominee Bob Stillman (Dirty Blonde, Grand Hotel) as Gould.
