This music is not on any offiicial cd of Vanessa-Mae. Nor did she ever play it in a concert, at least not to my knowledge. It is certainly not in her standard concert repertoire.
I saw your post in the forum already. In my opinion, Kazaa and other free music providers cause a lot of confusion in all this. Members that upload music to these providers make a lot of false assumptions in assigning certain pieces to Vanessa-Mae, and probably to other artists as well.
It is of course always possible that Vanessa-Mae played an unusual piece in a concert for some reason, but I have no information on Pachabel's Canon.
I have downloaded many things from Kazaa that are supposedly Vanessa-Mae but they are not. In my experience, there are many incorrectly titled downloads on the siteand it can be very misleading.
Best to take it with a "pinch of salt" as they say.
I'll call my contacts at Angel Records USA and see if they have any information. Often EMI keeps them in the dark but on occasion they are "in the know".
