So sad. We saw her (and Anna, Rufus and Martha, and Bruce Cockburn, and...others) in May at the Pete Seeger concert.

I remember her but forget what she had out. So sorry to hear about her. RIP...

The video of the performance at MSG seems to be gone now (sad, since I found it through their website), but here's another fun one -- with Rufus and Elvis Costello (whose show is GREAT if you've never seen it):
