John Stamos will be bringing his singing chops to a new realm, with a guest appearance set for “Galavant,” ABC’s upcoming musical comedy series. Stamos will appear as a rival to the show’s titular knight, played by Joshua Sasse.

“We are absolutely thrilled that John Stamos is joining us on the series as Galavant’s longtime rival — a dashing knight who squares off against him once more in a local joust,” says Dan Fogelman, the series’ executive producer. “We’ve wanted John to do an arc on this show since inception.”

While he is currently set to film one episode next month in England, there is a chance for the character to recur.

Stamos is best known for his role on “Full House,” but has recently appeared on “Necessary Roughness” and “The New Normal,” and has performed on Broadway.  Stamos also still tours with The Beach Boys.

“He’s funny as hell, and he sings, and he looks like Lancelot wishes he looked,” added Fogelman. “We can’t wait!”

ABC News first reported Stamos’ casting.
