Well, a bit misleading, that headline - kd lang is in fact selling the chance to record with her, and the proceeds of the eBay.com auction will go towards supporting the Ari Bhod foundation, an organisation dedicated to preserving ancient Tibetan cultural artifacts.
Lang is to cover Glen Campbell's 'Dreams of the Everyday Housewife' for a TV soundtrack. If the winning bidder is a great vocalist, the singer will duet with that person; and according to the auction info, if the winner has "a less-than-great voice, k.d. will work with you to get it to sound as good as it can and you'll probably wind up in the background-but your name will still be in the credits even if no one but people you personally point it out to will be able to hear where you're doing the singing."
