Hellooo Honeys...
This is an OLD question. In 1978, a war exploded between Pete Townshend and the then 20 yr. old Paul Weller, who claimed that the formed could NOT sing My Generation with the line "Hope I die before I get old" at the ripe old age of 33.
The funny thing is, he managed to send Pete into the deepest crisis: he wrote editorials to all magazines, started to believe that he was old, and, of course, like in all respected band there was the NO BULLSHIT guy (Roger) who said: Who is this guy and what has he accomplished? We are the 'OO! We'll be rocking in our rocking chairs.
Needless to say, Roger was right.
The issue is, making or performing good music is NOT a privilege of the young. There are so many shitty young artists that prove this, and that are only products of a savvy marketing campaign.
According to Harald FrankenFucker, B.B. King maybe should commit suicide... I suggest a heavy dose of watching the Clapton Chicago guitar summit (not to mention a Police concert) before writing such bull, that, ifv printed, it would have one use - in your toilet if you're out of paper.
