The Dr. Kildare star will perform at the 30th annual Southland Theatre Artists Goodwill Event (S.T.A.G.E) in Los Angeles and show off his vocal skills with a rendition of I Could Have Danced All Night, famously lip-synched by Audrey Hepburn in the hit 1964 film.
He says, "I said, 'Well how about I Could Have Danced All Night? It's very happy and upbeat. We had a rehearsal... with the musical director and decided how to present it."
Singer Debby Boone will also perform at the Saban Theatre event, which raises money for Aids charities in the Los Angeles area.
