When I was a kid the Beach Boys were my favorite too. Probably their car songs were the ones I liked best.
I think my favorite song of all time is “American Pie” and I still don’t know what it was all about except for Buddy Holly’s death.
As for my favorite song of all time, it changes periodically, but right now, it's Auch Du Wirst Mich Einmal Betrügen (You, too will betray me some day) by Ilya Livshakoff & His Orchestra, from 1930.
Something touched me deep inside Yarddog Hugs.
American Pie

Yes, it's still very listenable even after all this time. McLean has more poet in him than the average lyricist, but the American Pie album was exceptional even for him.
