Thats a Dead classicI started listening to the full run of the 1972 Europe shows (Yes, they released all of the complete shows (22 shows, 3CDs each) in a boxset and I believe they are also on spotify) but I gave up after like 5 shows or something. The Europe 72 live album is a great collection though of songs from that tour.
Yeah, I have that one downloaded somewhere, but I never heard it in its entirety. I think I never even heard the much more reasonable Spring 1990 as a whole and I am much more interested in that one ('cause Mydland, and also being the last great Dead tour - the latter ones were somewhat iffy and/or spotty, IMHO).
