David Duchovny was performing songs from his new album, "Hell or Highwater," in New York when he surprised the audience by inviting "X-Files" co-star Gillian Anderson onstage to help him sing Neil Young's "Helpless."

The show's initial run ended in 2002, but the pair still seemed to have plenty of chemistry, fist-bumping and dancing their way through the song. But the real treat for fans came at the end, when the on-screen partners shared a celebratory kiss.
