You wish you were there too when Yelawolf--Eminem's Alabama-raised protege--strutted up and down the Observatory's stage rocking dirty ass overalls. Things got heated while Johnny Cash's "Folsom Prison Blues" was playing; a concertgoer jumped onstage, got past security, and tackled down the rapper people refer to
as "Catfish." Yelawolf immediately got up, punched the fan, then got back into his set with gusto. Watch the video after the jump.
