I want to ask you something. I know that The Who in their early years (1964/67) used a kind of drug called drynamil. Can you tell me what drynamil is exactly? Drynamil was an amphetamine drug that was taken by many mods. It was = also known as leapers or purple hearts. It is basically cheap speed. The = stuttery lyrics of My Generation were meant to be representative of the = effect of amphetamines on mods.
