Did anyone in the music industry age as badly as Dave Gilmour? Not saying it in a dismissive way - he is and always will be a genuine artist at the guitar, but how many years would you say separated the first and second photos? 30, maybe - mid 20s on the left, mid 50s on the right? Perhaps 35, early 20s to late 50s? Nope, not even close. Try SEVENTEEN. The photo on the left is from 1978, during the recording of his first solo album, and the photo on the right is from 1995.
