Music writers talk about the punk explosion of the 70s as a reaction against prog rock, glam etc. and a political reaction. I think it was political, not musical. Some talented musicians like Elvis Costello and Sting used the energy of punk to get their music across, but the majority of punk bands had a very short life. Punk certainly didn’t sweep away prog bands like Genesis and Yes, who far outlived them (Genesis became bigger than ever). I think John Lydon was just having a big laugh (he went on to I’m a celebrity and advertising butter). The *** Pistols take on “My way” is very funny. Overall, punk doesn’t seem to have had much lasting effect.
