I have tons, mostly late 70's, including quite a few from '77, but mostly on tape. I have some on computer in MP3 that I might be able to send electronically, but not sure if those are '77-ish or not.
I was under the impression they shut down the archive for downloading and now it is to be streaming only?
I can totally appreciate why the band was having philosophical issues with the vault. Tape trading was always s'posed like, well, this--not a massive sight where you DL anything without ever talking to a human being.
If you don't mind getting some a bit late, I can send you tape, but only if you can copy them yourself and send the originals back, as I have no dubbing machine or equipement to computerize them.
Is there a particular show he is looking for? I'm not real up on my triivia, but that was a very good year. If I'm not mistaken they did a show at Barton Hall n Ithaca with arguably the best Scarlet>Fire sequence ever. Pretty sure that was 77.
Some stuff is also availabel for DL from itunes musice store (link from apple.com, I think) but that is problematic as they break it up into tracks, and then the software constantly shuffles the order, destroyingt he integrity of the show.
