Task: Question Generation
Input (English): Passage: In August 1975, Rhodes spotted nineteen-year-old Kings Road habitué John Lydon wearing a Pink Floyd T-shirt with the words I Hate handwritten above the band's name and holes scratched through the eyes. Reports vary at this point: the same day, or soon after, either Rhodes or McLaren asked Lydon to come to a nearby pub in the evening to meet Jones and Cook. According to Jones, "He came in with green hair. I thought he had a really interesting face. I liked his look. He had his 'I Hate Pink Floyd' T-shirt on, and it was held together with safety pins. John had something special, but when he started talking he was a real arsehole—but smart." When the pub closed, the group moved on to Sex, where Lydon, who had given little thought to singing, was convinced to improvise along to Alice Cooper's "I'm Eighteen" on the shop jukebox. Though the performance drove the band members to laughter, McLaren convinced them to start rehearsing with Lydon.Lydon later described the social context in which the band came together:
Early Seventies Britain was a very depressing place. It was completely run-down, there was trash on the streets, total unemployment—just about everybody was on strike. Everybody was brought up with an education system that told you point blank that if you came from the wrong side of the tracks...then you had no hope in hell and no career prospects at all. Out of that came pretentious moi and the Sex Pistols and then a whole bunch of copycat wankers after us.
Their first gig was arranged by Matlock, who was studying at Saint Martins College. The band played at the school on 6 November 1975, in support of a pub rock group called Bazooka Joe, arranging to use their amps and drums. The Sex Pistols performed several cover songs, including the Who's "Substitute", the Small Faces' "Whatcha Gonna Do About It", and "(I'm Not Your) Steppin' Stone", made famous by the Monkees; according to observers, they were unexceptional musically aside from being extremely loud. Before the Pistols could play the few original songs they had written to date, Bazooka Joe pulled the plugs as they saw their gear being trashed. A brief physical altercation between members of the two bands took place on stage.
Output (English): What are the full names of the two bands between whose members a physical altercation took place on stage?
