#1 for the week of 1/16/71: George Harrison, "My Sweet Lord." Still in awe of the slide guitar and the backing vox arrangement on this.
I am SOOOO glad you got to hear the entire 40 -- truly amazing stuff. A treasure trove of you-NEVER-hear-these-songs-anymore mind-bogglers. I'd never heard that BJ Thomas tune, and isn't "Games" by Redeye the best CSNY imitation evah? And the Curtis Mayfield -- hoo lawd! Plus Elvis, the Edwin Starr "War redux", Ray Price, and on and on.
AT40 didn't begin airing in NYC until March of '71 so this was truly a show I'd never heard before. Didya notice the suble difference in Casey's voice? A bit gruffer. It took another 6 months to a year before he got into his sincere/syrupy groove. Assuming KFRC continues the shows, I'm hoping they replay the very first show (July 4th 1970) when the time comes.
Chart addendum: the Harrison is indeed shown as "My Sweet Lord/Isn't It a Pity" thru-out its run. And the Elvis was double-sided too.
