Glam really did plant seeds for a new identity. I think a lot of kids needed that - that sense of reinvention. Kids learned that however crazy you may think it is, there is a place for what you want to do and who you want to be.
When it comes down to it, glam rock was all very amusing. At the time, it was funny, then a few years later it became sort of serious-looking and a bit foreboding.
