Well, not exactly new per se, but it's new to me.
I recently ran across a recording of James Taylor playing a solo show at the Berkeley Community Theater from May of 1970. Decent recording, and it's got a number of the Sweet Baby James-era hits included, as well as covers of Joni Mitchell's For Free and Merle Haggard's Okie From Muskogee (small bit of irony in the latter--who knew JT could be ironic?).
What I find really interesting, though, is that midway through the set, he introduces a woman to come out and play piano with him--it's Carole King. What's funny is she gets polite applause, but being as Tapestry wouldn't be released for another 10 months or so, it's nothing near what I expected to hear. Then he introduces her singing "a song she wrote with Gerry Goffin in 1962, Up on the Roof" and still, polite applause but not nearly what I'd have expected. Wonder how many of the people in the audience would, 18 months later, be boasting of having seen Carole King and James Taylor on the same stage?
Just had to share that with someone, and I knew you guys would appreciate.
