The nine-day cruise is titled the Composer's Cruise and will feature Broadway composers Leslie Bricusse, Stephen Schwartz and Frank Wildhorn, who will perform in concert with such theatre favorites as Liz Callaway, Rob Evan and Brandi Burkhardt (other performers will be announced shortly). "Guests," according to press notes, "will experience exclusive shipboard concerts and events with the songwriters and performers culminating in a special finale concert in beautiful Monte Carlo, France. . . . This Composer's Cruise will mark the first time that these three songwriters will ever share the same stage."

The entertainment on the cruise of the Mediterranean will include "The Music of Frank Wildhorn" (Oct. 29), Master Class (with Schwartz and Wildhorn) (Oct. 31), "The Greatest Hits of Stephen Schwartz" (Nov. 1) and "Once in a Lifetime" (Nov. 2).

The ship is the 700-guest Seven Seas Voyager, which features four main dining venues.
