I just acquired the CD Gershwin's World, in which Herbie Hancock rounded up a number of artists to interpret a selection of works by George Gershwin. Joni performs "The Man I Love" and "Summertime". Stevie Wonder also does a couple of numbers. There is even a Gershwin-influenced work by Maurice Ravel. I have really enjoyed this CD. I got the idea to buy it from an interview with Joni I read on the website.
