If you haven't checked out Kayla Williams, I suggest you go here:
http://www.youtube.com/watch?v=YLAjIOreRegShe's made about 15-20 BB covers - all beautiful!!!
And here's a mix I made - that's Kayla doing Wouldn't it be nice on top of the original BB backing track,
that is, Kayla & the Wrecking Crew. Had to do some slowing down of the backing track and some splitting
of the Kayla vocal/piano track.
