The problem with bootlegs is that the same material is "released" under different names. It can differ from country to country. I think that one of the bootlegs was called "Live 67/68" or "Studio 67/ Live 68". Google, and you'll find it and probably more.
Don't expect the sound quality of bootlegs to be a lot better. The tapes used for bootlegs are usually unmixed and therefore rough, uneven sounding, even studio recordings. Also the producers of bootlegs were often just in for a quick buck and didn't care much for transferring the tapes well unto vinyl.
But who cares about sound quality? Way back I heard "White Rabbit" for the first time on a lousy transister radio and loved it!
