A few tunes follow expressing various reasons for giving thanks. (Also note: I posted earlier the greatest of them all, Beethoven's "Hymn of Thanksgiving"). Kicking off with the very seasonal, "King Harvest" by The Band in amazing live in studio version.
From Sam Cooke, one of the true greats, from his gospel days, with the Soul Stirrers, 1950s, mentioning everything from flowers to kids on the street.
Then very early Led Zep in one of the few songs actually titled "Thank You." Though there's also Natalie Merchant's.
And, of course, we then have to let Sly Stone thank you for letting him be himself again (and in his case, again and again).
