Watch Sammy Hagar Rock Some Gnarly Dad Cargos While Jamming With Dead And Co’s John Mayer

Last night Dead and Co played an intimate set in The Grateful Dead’s iconic 1960s hangout, The Fillmore West. A couple days earlier, however, some magic went down when The Red Rocker himself crashed a Dead & Company rehearsal. With John Mayer channeling his inner-Stevie Ray Vaughn and ripping the shit out of some blues rifts through the tube screamer, Sammy Hagar sang along like the boss that he is. I especially love Hagar’s dad cargo shorts.

Those are the shorts of a man who definitely fucks. Long live The Red Rocker, one of Nor-Cal’s many wonderful exports to the world.
