Stan Rogers Mariposa 1975? Concert

So, I recently found this one because another youtuber posted the excert from Fat Girl Rag from this concert and the link to where they found it. However, they didn't post the full thing, so I thought I'd just do it myself.

The concert is probably from 1975 but I can't say for certain, Stan does mention Robbie McNeill performing earlier, who does have an accessable recording from 1975.

The photo is of Stan at Mariposa in 1975, again I've no idea if it's the same year as this performance is from unfortunately. I can find very little and can't actually access it on the York University archives where I believe it was originally downloaded from. Interestingly, the website says only 10% of their material is digitised which means there may be more things to come (eventually) or that exist but are locked behind certain permissions. If you want to explore for yourself, I've linked the archive below.

Finally, a higher quality of download of this concert can be downloaded here, rather than having to rip it from this youtube video:

Typing the url manually indicates that the page exists but there is no access unfortunately, if anyone has an account or wants to try, the link is: https://digital.library.yorku.ca/mari...

The Robbie concert that features Evangeline and may have happened just before is still available:
