60's, 70's and 80's Music
From Thikipedia
Music from the 60's and early 70's is currently extremely popular. The most famous group of this age is The Rolling Stones, shown below. From left to right, the group comprises Ron Wood(60), Mick Jagger (63), Keith Richards (63) and Charlie Watts (65).
80's music is less popular as most people's skin becomes too wrinkley to play guitar properly at this age.
