But right now, that old nugget from 44 years ago is The One in my biased opinion. There's live versions by the Stones and all manner of guest vocalists from Lady Gaga and Fergie to the awesome Lisa Fischer, but they are no match for Merry Clayton the original backup singer.
This was a tune of it's era - more Altamont than Woodstock, as The Singer once said:
"Well, it's a very rough, very violent era,
Violence on the screens, pillage and burning.
And Vietnam was not war as we knew it in the conventional sense..."
"That's a kind of end-of-the-world song, really.
It's apocalypse; the whole record's like that."
