The cast will go into the recording studio Nov. 14. No release date has been scheduled.

A limited number of tickets to the one-night-only event — directed by Tony Walton — are still available. The starry evening will boast the talents of former Barnum co-stars Jim Dale and Glenn Close as well as John Bolton, Cristy Candler, Bob Fitch, Jessica Grové, Michael Hall, Elizabeth Inghram, George S. Irving, Noah Racey, Anne Rogers, Michael Lane Trautman, Diane Wasnak and Patrick Wetzel.

The creative team also includes Lisa Shriver (choreography), Richard Pilbrow (lighting design) and Aaron Gandy (musical direction).

Busker Alley, according to press notes, is “about a busker (one who entertains in public on London’s famous streets) who falls in love with a much younger woman who longs to be a big star in the theatre and leaves him to follow her dreams.”

Based on the 1938 British film “St. Martin’s Lane,” Busker Alley features music and lyrics by Richard and Robert Sherman and a book by A J Carothers. Tommy Tune starred in a pre-Broadway tour of Busker Alley in 1995. Six weeks prior to the musical's Broadway debut, Tune broke his foot during a performance in Tampa, and the show never reached New York.

Tickets for the benefit, priced $100-$250 (the latter includes admission to the post-show reception with cast), are available by calling (212) 772-4448 or by visiting the Kaye Playhouse box office, East 68th Street between Park and Lexington Avenues.
