I've liked the Clash since the 70s. My sister (I think) had the London Calling album and I loved the variety of stuff they did along with the raw energy of their punk rock sound. It wasn't until a few years ago that I saw a video of the another cover of this song from the 60s. I had no idea it was a cover and always assumed it was 100% Clash but it's not, it's by Sonny Curtis and the Crickets (post Buddy Holly death). Anyway, The Clash's version is just exploding with aggression and energy and I love it. You should too!
