darlene love tears it up
One of the episodes of Letterman that was mythed while I was gone was one with Darlene Love, one of Phil Spector’s singers. She sings Christmas (Baby Please Come Home) a song she was the original singer of. And she just tears it up. It’s pretty impressive that she can still belt it out at her age.

(You can also check out the U2 cover of the same song from back in the Bono-has-long-hair-and-wears-dumb-hats phase.)
