Its true to say that each generation has their own music that helps to define their place in society as they create new things for themselves. Think back to the time when we were all young and the reaction to "our" music ranged from indifference to hostility.
I don't see this forum as a place for me to make comparisons between Cliff Richard and The Shadows, The Beatles and their contemporaries other than to say that I believe them to be obvious and true. That's not a comparison of good or bad by the way, and nor am I capable of an academic study of this so I'll just turn up the volume and continue listening to the wonderful Shadows CD, Specs Appeal, coz that's my music after all.
