I hear what you are all saying .......BUT
whatever it sounds like and whatever anybody thinks of the manufacturing of a band, at least they are singing a decent song, not a pile of repetitive rubbish that means nothing, and keeping the tradition alive - after all who's to say Robert Burns isn't turning in his grave at the renditions that some of his songs get for example.
The beauty of a living tradition is that it lives, breathes and moves on, the best in your eyes may be the worst in anothers, and for the kiddie generation this IS the first time they have heard it and when they hear Simon and Garfunkel's version will screw their noses and say I like it the way HearSay do it - We are probably all guilty of that, having heard a version and learned it, it is difficult to re-learn another version - and easy to prefer the one we learned!
Just a thought or two from an old traditionalist!
