In Hallmark's "Perfect Harmony," James Denton and Sherri Saum perform the duet — aptly titled "Perfect Harmony" — and Denton also goes solo to belt out "Ooh Wee Ooh." The original music was composed by Jack Lenz, per Variety.
Fans of Denton are familiar with the actor's musical talents. He plays guitar and sings in Band From TV, which consists of actors and musicians who perform cover songs at live events for charity. Some of Denton's fellow bandmates include Greg Grunberg from "Alias" and "Felicity," Jesse Spencer from "Chicago Fire," Adrian Pasdar, from "Agents of Shield" and "Heroes," and Scott Grimes from "Orville." Through the years, the band has raised almost two million dollars (per Hallmark) in funds that have gone to charities including Conservation Fund, Children's Hospital L.A., The Epilepsy Foundation, The Art of Elysium, Save the Children, and more.
"James Denton brings the Springsteen (or) Elvis quality to the band, so you'll hear 'Mary's Place' from Springsteen, you'll hear 'Viva Las Vegas,'" Grunberg told The Orange Country Register about coming to one of the band's shows.
