Watch a clip of Stevie Nicks joining Deer Tick live onstage for a rendition of "Rhiannon"

Sharon Van Etten was one standout pal that jumped onto guest vox duties, covering "Perfect Day", originally by Lou Reed, with Deer Tick.

Footage has now emerged from their New Years Eve finale, where they performed fan-selected tunes. Stevie Nicks has joined the band, aiding in a version of Fleetwood Mac ditty "Rhiannon."

As Stereogum note, "Nicks is a long-time friend of the band: Last year, she officiated frontman John McCauley’s wedding to Vanessa Carlton."
