"Super Marios Brother's" with John Williams and the Boston Pops

This is one of those classic huh? mp3's that have been floating around the internet for a while: John Williams conducting the Boston Pop's Orchestra in a lovely rendition of the theme song to "Super Mario Brothers."

If anyone knows where this mp3 came from, please post in the comments. I acquired this track from a friend ages ago and would love to have the source disc. I don't think this is the same ensemble as the 1993 Alan Silvestri album.
