Boy George and US movie star Jack Black have covered The Doors' Hello, I Love You with the band's guitarist Robby Krieger.
Whilst both Boy and George were on American TV show Conan, hosted by Conan O'Brien, Black said: "Jim Morrison [lead singer of The Doors] had the best yell."
This lead O'Brien to invite the pair to cover The Doors' celebrated classic Hello, I Love You.
After both stars agreed, suddenly the former Doors guitarist Robby Krieger turned up on stage with his guitar to join the rendition.
