This Circus July 1975 article I overlooked when I initially posted
I plan on updating that page too.
This article talks about the compilation album that includes "I'm Eighteen"
I had this LP but ended up selling a number of my vinyls back in the 80's
that I kick myself over now. Only good thing is I didn't sell all my LPs
I sold or traded 500 but I still have about 500 vinyls left in my collection.
I found a pic online of the double album
