The Grateful Dead’s legacy is rich enough to merit a four-hour documentary that includes an appearance from Al Franken, the former “Saturday Night Live” performer and current United States senator who didn’t “get” the druggy cult surrounding the band. HuffPost has an exclusive clip from “Long Strange Trip: The Untold Story of the Grateful Dead” in which Franken recalls dirty scenes at Grateful Dead shows with all the charm of a primo dad. 

“Long Strange Trip” opens May 26 in New York and Los Angeles, and premieres June 2 on Amazon Prime.
