The Daily Record, a newspaper in Scotland, has found a recording of Susan Boyle singing "Cry Me A River" on a charity CD that came out in 1999. The CD was to benefit Whitburn Academy, a high school near Boyle's home in West Lothian, and only 1,000 copies were ever burned. I assume it's high Internet traffic that is not allowing me to hear any more than a few seconds at a time, but maybe some of you will have better luck.
Also, for all the commenters who were so upset about the media's obsession with Boyle's appearance (another interesting discussion can be found here): The website Daily Makeover has come up with two new looks for Boyle. Users can vote on their favorite, though some have taken the makeover initiativethemselves.
In the Daily Record interview, Boyle has said that she expects Britain's Got Talent will do something with her hair and makeup, but Susan, please, don't succumb to the flatiron. Please stay as much as you are as they'll let you.
