Oh, The Clash, this is one of the few times where learning more background about a song makes me enjoy it even more. I mean, I think this song is awesome as is, but the story behind the title, taking a train to visit your girlfriend and coming back grumpy, added with the bitterness of the lyrics, that’s great stuff, The Clash. And as crummy as you obviously feel, it’s got to make you feel at least a little better that all those negative emotions were channeled into an awesome song, right?
