It's lovely, but it's been posted before.I can't let the progressive rock genre be underrepresented in this thread. How 'bout Procol Harum's A Whiter Shade Of Pale (1967)
He's had so many great songs, and, yes, many of them indeed beautiful.(Formerly) Cat Stevens, "Oh very young" - from Buddha and the Chocolate box. Brilliant.
....and Johnny B. Bach's "Aire on a G String" redone on by some English lads with a saturated Hammond B-3 and who knows what else....
