I do a few of these but most I've never heard of.
Now if you want to talk about some they missed....House of the Rising Sun (Animals), Green Onions (Booker T and MGs), Honky-Tonk Bill Doggett), Behind Closed Doors (Charlie Rich), Last Date (Floyd Kramer), Wha'd I Say (Ray Charles), Georgia (Ray Charles), Whole Lotta Shakin (Jerry Lee), Desperado (Eagles), ...these just come to mind and all have unforgettable keyboard intros. Once you hear the intro you know what's coming.
I agree about Whiter Shade of Pale--what a great song, even if the words don't make much sense. How 'bout Crocodile Rock? Somebody stop me, I know just enough to get in trouble.
