You guys have got to see this website!
It is a national classic rock concert website. It lists practically every rock concert that has ever taken place in the United States. If you register (I did, as DavifF1957) it lets you enter comments regarding any concert that you may have attended.
I commented on the 1979 Who concert at Masonic, as well as one Stanley Clarke played there in 1979.
It even lets you add concerts to the database. I added an Amboy Dukes concert that I attended at the Michigan Palace in 1974!
Way cool!
