On the Jan. 28 episode of the reality competition series, fans saw the British impresario get the call from Grease creator Jim Jacobs to join the judges' panel, which also includes director-choreographer Kathleen Marshall and British producer David Ian. Lloyd Webber guests on Feb. 11 when the show returns for another two-hour live episode 7-9 PM (ET). Check your local listings.

The results of America's voting will be revealed and the first Sandy and Danny hopeful will be cut. The remaining 12 finalists will perform for the Broadway-themed episode which will feature half of the contestants singing songs from Andrew Lloyd Webber musicals and the other half from other popular musicals. (Voting will continue during the Feb. 4 repeat episode.)

Among Lloyd Webber's musicals are Joseph and the Amazing Technicolor Dreamcoat, Jesus Christ Superstar, Evita, Tell me on Sunday, Song & Dance, Cats, Starlight Express, The Phantom of the Opera, Aspects of Love, Sunset Boulevard, Whistle Down the Wind and The Woman in White. The composer served as judge on BBC's similar "How Do You Solve A Problem Like Maria?" competition show.
