Bobby Gillespie joins J Mascis onstage for a run through The Stooges' 'No Fun' - but events take an unexpected turn...

PRIMAL SCREAM frontman BOBBY GILLESPIE allegedly attacked a concert goer with a microphone stand during a show at LONDON SHEPHERD’S BUSH EMPIRE on Friday (June 8).

Eyewitnesses say Gillespie climbed onstage to join J Mascis & The Fog during the latter part of the former Dinosaur Jr leader’s gig. He guested on vocals working through a cover of The Stooges‘ ‘No Fun’. At some point, a concert goer is said to have started to barrack Gillespie and he reacted by grabbing the microphone stand, jumping from the stage and attacking him.

The man’s identity is unknown, and while no one was able to confirm to NME.COM the extent of his injuries, one source said he was left bleeding. Gillespie disappeared and did not rejoin Mascis at any point.

Gillespie could not be reached through his spokesperson for comment at press time. A spokesperson for Mascis did though confirm that the incident had happened.

Mascis completed a brief UK tour with a show at the Brighton Pavilion the following night (June 9).
