While Machine Head clearly enjoyed the show, both on the stage and in the crowd, security didn't take too kindly to a copulating couple on Thursday night.
The California based heavy metal rockers returned to San Diego after an 11-year absence, telling fans on their social media that the city is "un-fired" following the greeting they received.
The band revealed that they knew what they were in for, writing, "When a guy and gal get ejected for having sex during 'Davidian' (in the front row no less!?) you know it's gonna complete insanity!"
It must have been hard for the band to pick one highlight from the gig, so they listed them all: "Epic circle pits, the jumping was crazy, boobies, sing-a-longs, crowd-surfing-mania, couples having sex!!?"
