In Danny Boyle's Trainspotting, the movie that introduced Iggy Pop to '90s kids like me, there's a scene where Renton and Sick Boy are splayed out in a park with an air rifle, and Sick Boy is explaining his unified theory of life to Renton: "At one point, you've got it. Then, you lose it. Then it's gone forever." Reeling off examples, he mentions two of the names in the proto-punk holy trinity: David Bowie and Lou Reed. The one name he doesn't mention is Iggy Pop, the only one of those three left standing. (At another point in the movie, Renton has to explain to a teenager that Iggy Pop is still, in fact, alive.) The Scottish junkies of Trainspotting wouldn't have made that point about Pop; in Irvine Welsh's original novel, they all regarded him with a certain religious veneration. But the theory fit Iggy Pop way better than it ever fit Lou Reed or David Bowie.
