The snarling singer, aka Sex Pistols frontman Johnny Rotten, was performing with his band Public Image Ltd at Club Blondie in Santiago, when a fan hurled a glass bottle towards the stage and hit Lydon on the head.

With blood pouring from the wound, the This is Not a Love Song singer scowled "What a f**king coward" at the unidentified bottle thrower, before wrapping a towel around his head to stop the bleeding.

After a short pause he returned to the microphone and announced, "We continue!"

Lydon posted a photo of himself backstage after the gig on Facebook on Monday (15Aug16), adding the caption: "Glass attack last night at Santiago, Club Blondie in Chile. No reflection on the rest of the crowd. Great gig. It lives."
