All 1975-1976 concerts on tape?

[Moz]

I'd like to know (or at least have a rough estimate) of how many filmed concerts from 1975-1976 are floating around. The only one I know of is the Largo show and Midnight Special appearances! The only pre-1977 concert I have is the Rosebud film and a few things from Midnight Special.

PS. If anyone out there is willing to do a (2-1) trade with me for filmed shows, let me know! I'm interested in anything pre-1982, especially White Album era and anything before Stevie and Lindsey joined. The only shows I have in whole are the Tusk documentary and a Mirage show. I'm willing to take almost anything!
