I know this has been said but this is one of the best songs ever. The Beach Boys were my parent's band but me and my 2 sisters loved them too. Good Vibrations was always my favorite. ADVICE: If you are sad, listen to the Beach Boys!
Crackin' pop song . . . I love both versions, but the 60s version obviously is so well known that there would be a predictable reaction, with vociferous differences of opinion. At least it's not like Madonna doing a cover of American Pie (though perhaps that's not the worst example of cover versions?)
