1. Iggy Pop
Some people are just made of different material to the rest of us, and Iggy is clearly one of them. Wondering quite how he's still alive is one of those long discussions that everyone has had with music-loving friends over the years. Iggy's drug use made him one of the best front men of all time whilst a part of The Stooges, but eventually led to a number of drug overdoses (including one on stage) and a stint in a mental hospital. However, he's since managed to clean himself up, and not much of note musically has been heard since, aside from a couple of songs on other bands albums, and a reformation of The Stooges, but many of their best songs have long since been recorded. https://www.youtube.com/watch?v=IFe0OfEtP2w
