If you listen to youtube you'll find covers by 20 and 30 years olds of Blind Faith, Beatles, etc. Dark Side of the Moon was on the charts for 491 weeks. Cat Stevens came out of hibernation and issued a current version of a classic half a century old album.
Think any current group will break the record of Dark Side? How much current music will be around in half a century?
