Before we begin, it should probably be noted that relating the story of UK punk in any less than about 4,000 songs in pretty much impossible. From The Adicts and Angelic Upstarts to Zounds and The Zeros, Wikipedia lists well over 100 UK punk bands, and their list is woefully incomplete, omitting Defcon Zero, Vortex, Sick On The Bus, The Satellites and many, many more. Further selecting the definitive song by each band is an equally thankless task. It's easy enough with bands like Menace (that would be G.LC.) or Cult Maniax (Lucy Looe), but what about The Lurkers, Subhumans, or 999 who each had several classics to their name? What about Anti Nowhere League, Wire, and The Mob? All of them punk, but all very, very different.
Moreover, what began simply as punk rock rapidly diverged into multiple subcategories – from hardcore and crust to anarcho-punk, pop-punk, street punk, horror punk, and numerous other variations. And that's before punk and metal hopped into bed together and started producing obnoxious bastard offspring!
