Two days before its Sept. 16 seventh-season premiere, Will & Grace is releasing a companion CD, Let the Music Out!. Along with previously released material by performers such as J. Lo, Cher and Elton John, the album will include several new recordings. Among them are "Living with Grace," a duet between Barry Manilow and leading man Eric McCormack; a cover of Carly Simon's "Loving You's the Right Thing to Do," sung by Simon and Megan Mullally; and "He's So Hot!" featuring the whole cast, plus a sample of guest star Madonna's "Holiday." Don't you just know that somewhere Sandra Bernhard is fuming; she did the show twice, after all!
