Sick Boy: It's certainly a phenomenon in all walks of life.
Mark "Rent-boy" Renton: What do you mean?
Sick Boy: Well, at one time, you've got it, and then you lose it, and it's gone forever. All walks of life: George Best, for example. Had it, lost it. Or David Bowie, or Lou Reed...
Mark "Rent-boy" Renton: Some of his solo stuff's not bad.
Sick Boy: No, it's not bad, but it's not great either. And in your heart you kind of know that although it sounds alright, it's actually just s**t.
Mark "Rent-boy" Renton: So who else?
Sick Boy: Charlie Nicholas, David Niven, Malcolm McLaren, Elvis Presley...
