Does anyone know of a video version of Joni Mitchell singing Circle Game? I have an audio of her and James Taylor doing it on a (I think) Canadian TV show from a long time ago ("All Star Tribute to Joni Mitchell" ???).

I'm going to try an play it at my daughters wedding and I'd like to see her do it. I've got some tabs for it and I'm getting some help from a pro but I'd still like to see Joni's hands go through the progressions to see if I can pick up any nuances, particularly her right hand.
