Song rumored to me actually hated be the band members for being to "poppy." I think its one of their best recordings. You be the judge. The Clash was always the least punk of the first wave of punk bands which included the Ramones and the Sex Pistols. They mixed genres like reggae, ska and politics to come up with a sound far more original than the other two bands. This is them at they're bubble gum best.
