You should worry about age-I saw Def Leppard in 1979 when the average age of the group was around 16. My fav group Deep Purple released their seminal Machine Head album 37 years ago, and reformed after the original break up 25 years ago.
Oh and John Bonham of Zep has been dead for 29 years.















29?! I remember the news blowing around school and Tim Mannings going into mourning. I didn't get into Led Zep until the mid-90s - always last on the bus - so received the news with minor nonchalance.
