VIDEO : Bob Saget and Carly Rae Jepsen Sing Duet of Fuller House Theme Song

When Fuller House debuted on Netflix, the show not only introduced a new generation of fans to the revamped sitcom, but also to a refreshed theme song, recorded by Carly Rae Jepsen . During the singer's concert in Milwaukee, the Full House fandom came full circle when the sitcom actor synonymous with Danny Tanner hopped on stage to join the pop star for a nostalgic surprise. Bob Saget had serendipitously wrapped up his own comedy show in the area before joining Jepsen.
