Before their massive double-headlining show at New York City’s Terminal 5 last night, Snoop Dogg and Wiz Khalifa performed a jingle bell-laden version of “Young, Wild and Free” on Late Night with Jimmy Fallon. The collaborative soundtrack for their Cheech and Chong-style movie, Mac and Devin Go to High School, is slated for release on December 13th, but the actual flick still has no official release date.
