I will go with ROIOS for each year, not necessarily specific gigs for this one.
1967 - BBC Archives 1967-1969 (have to include this for the Syd material)
1968 - The Live Pink Floyd (Rotterdam) - poor sound, but great set list
1969 - Complete Concertgebouw ('nuff said)
1970 (my all time favorite ROIO, period) - Interstellar Encore - absolutely stellar performance, even though Dave blows the lyrics for "Green is the Colour," astonishing soundboard quality, the crowd is into it, and even Roger is clearly in a great mood. Absolutely devastating versions of "A Saucerful of Secrets" and "Interstellar Overdrive." This one is so good that I almost feel as if I were sitting right next to the taper in the Fillmore.
1971 - Meddled or Electric Factory
1972 - (impossible to find pre-Darkside shows, as the first dark side gig was at Brighton Dome in January!) - Cold Front (Hokkaido Arena, Sapporo Japan)
That should about do it.
