Ah Richard got there before me - that would be my suggestion as the prices from the usual outlets are really lumpy and I can't see any Hi Res downloads. With Discogs you'll need to check through the issues for the 2005 remastered edition (the one with George on the font in the white suit). Find someone in Europe approaching 100% Rating and a Near Mint to Mint then watch out for the postage as this is 2 CD box and might be a deal breaker for you. I've used the Discogs platform to find that ' hard to come by CD' and always been happy.
It's well worth having this great album - I love the bit where Ravi Shankar starts up on the sitar then stops a few minutes in with Madison Square Gardens going wild. Only for Ravi to say I hope you like the rest of my set as I was only tuning up!
