I found out in my early 20's that "This Land is Your Land" was not a song that had existed forever, but was written only about 50 years earlier, in 1945. (And Guthrie's original recording of it is much, MUGH harder hitting than a bunch of kindergarteners singing it.) "Bridge Over Troubled Water" feels kind of the same, like it must have always existed. But no, here it is for the very first time, in glorious stereo. And it, too, is now a little over 50 years old. Kind of crazy.
