I loved that song when it first came out because it was a blast to dance to and just generally fun.
Now I love it for the lyrics. ;)
I saw the Clash 3 times live. All amazing concerts. Extreme leftists but they could rock with the best of them. They didn’t do too much chatter between songs. I think the template for punk rock was set by the Ramones who basically did short songs followed by a short pause and then 1234 go! right into the next song. In their heyday a Ramones concert was non stop energy and the rest of punk rock followed.
In this case the song fits as it was inspired by the ban on Western music in Iran.
