Buddy Rich DVD Help

[Marcos]

Sorry if this has been asked before, I did a search with no luck. Regarding "The Lost Tapes" dvd. I am finding 2 differently packaged dvds and am wondering if they are the same content-wise. One is called "The Lost Tapes" and the other is "The Lost West Side Story Tapes". The track titles/set-list appear to be identical. I am guessing one of these may have additional features since there is a large difference in the price range, but I cannot confirm this. Anyone?
