A new promo for "Legends of Tomorrow," the third series set in the CW's shared "Arrow"-verse, has arrived online. This one focuses specifically on the team's mission to 1975 and comes complete with a soundtrack provided by classic '70s rock song, "Bang a Gong (Get It On)" By T. Rex. The clip features a young Martin Stein, one that seemingly takes a liking to White Canary (Caity Lotz), and Rip Hunter (Arthur Darvill) pleading with his recruits to stop punching him in the face.

You can check out the retro-flavored trailer below; "Legends of Tomorrow" debuts on the CW on Thursday, January 21.
