While the Rams <> Seahawks NFL game played on the TV, I found a link to a website that has researched and recently rebuilt the Classic Rock show history at the Fillmore West in San Francisco. I stumbled on it due to that thread asking about hippie stuff. There had been an earlier website that listed many of the shows but there were lots of unknown holes in that calendar. The new listing that was built with spread sheet separators is thorough. So I copied the data of just the period I was going to shows into Excel and then used my word processing and Excel skills to rebuild that into a much more organized Excel chart.
I captured a crude Pixel image off my computer screen that is the barely readable below haha. Difficult to read the crude photo of my work but enough to get the idea.
This was a typical line of information I used for the chart:
27 August 1970 Fillmore West, San Francisco, CA John Mayall, Elvin Bishop, Herbie Hancock Lights: Little Princess

After awhile, once the show sequence was correct, given the way human memory works sequentially, amazingly I've been recalling quite a bit. Of the 140 listings, I only recognized about 100 of the music group names as some were more obscure to me second and third acts. Music would sometimes go way into the wee hours. But I might recall more with some name and photo web searching. I usually would only go to one show during multi date show dates. Although I don't always recall every group name, I do recall attending almost every one of the shows.
One of the things I just recalled after looking at the web page show sequence was
Iron Butterfly had been on the marquee with their famous
In A Gadda Da Vida, on the date just previous to when I first saw a show there that I wished I had been to. Later that decade did catch them at another venue.
