ABC has signed judges, cast and a host for its new competition series Sing Your Face Off, and it’s quite a unique collection of famous names.

First, actor John Barrowman (Torchwood, Arrow) will host the show, where five celebrity contestants take on the identity of an iconic music performer each week.

The judges are former Saturday Night Live cast member Darrell Hammond and pop singer Debbie Gibson.

And the show’s contestants learning to perform the hits of famous music stars are ex-Skid Row frontman and heavy metal singer Sebastian Bach, comedian Jon Lovitz, Toronto Raptors player Landry Fields, teenage Disney Channel actress-singer China Anne McClain and former soap star Lisa Rinna.

Of all the performers above, fans are probably most surprised to see Barrowman listed. He may be best known in the U.S. for his roles on cult-favorite sci-fi shows, but he’s hosted and served as a presenter on several unscripted shows in the UK.

The six-episode Sing Your Face Off is produced by Endemol USA with Georgie Hurford-Jones (America’s Got Talent) as executive producer and based on a successful international format. There’s no air date yet, but the production seems to gearing up for a potential debut this summer.
