Mark Knopfler sat in with Bob Dylan at Las Vegas’ Mandalay Bay Events Center on Saturday night. The Dire Straits frontman is currently touring as Dylan’s support act but has only sat in with him on one other occasion this fall. On Saturday night, Knopfler emerged for “Beyond Here Lies Nothin,” a song off Dylan’s 2009 album Together Through Life. Like most songs off the release, Dylan co-wrote “Beyond Here Lies Nothin” with Grateful Dead scribe Robert Hunter. While not a rarity, Dylan has shied away from playing the song on his fall tour.

Dylan and Knopfler will kick off a two-night run at Broomfield, CO’s 1st Bank Center tomorrow.
