The Boot-les

Well, Yesterday, I found in a music store in Downtown Bellingham a bootleg CD of The Beatles' rooftop concert.  Since I had never seen such a thing in person, I chose to purchase it.  Overcome with "the fever," I downloaded a version of The Beatles' Budokan concert in Tokyo, June 30th 1966.  However, something doesn't sit too well with owning the second, since two of the tracks (the bootlegged duplicates of which I deleted) are already available in Anthology 2, which I own.  I'm wondering what your thoughts are, delete all the recordings from Japan, some (I'm especially fond of the live version of "I Feel Fine"), or none?
