I doubt that anyone knew it at the time, but the bass line for Rock the Casbah was genius, and to this day, it's a goto practice tune for me, because it's SO much fun solo. And, difficult to play fluid.
I still can't believe that these guys, who admittedly couldn't play a note and half the time were wasted, were able to come up with this stuff. I have to believe that studio staff wrote and in most instances recorded it... but even if so, hat's off to Paul and Sid for then learning them!
Often when someone new joins the band and we tell them that's what we play, they always get so puzzled, then without fail, after the first set, they're yelling let's play that Sex Pistols tune again! It's fun x2
