From the Letterman show in 1992, please enjoy Carole King on piano (in one of the most amazing all-star bands of all time) and a mind-boggling performance of Bob Dylan's "Like a Rolling Stone."
I should add that King is one of my all-time favorite rock keyboard people ever, apart from being an astounding songwriter. She's having a hell of a good time in that clip too, isn't she?
BTW -- that's Chrissie Hynde on rhythm guitar in the back. And the vocal section is Mavis Staples, Michelle Shocked, Roseanne Cash, Nanci Griffiths and Emmylou Harris.
Words fail me.
