This awful bootleg has been issued and reissued for over 30 years. I have it on LP. It's an amateur recording made at the September 13, 1969 Toronto Rock 'n' Roll Revival held at the football stadium of the University of Toronto.
Why does it sound so bad? For one thing, the concert promoter (Detroit's "Uncle" Russ Gibb) was a cheapskate, and provided only the minimum P.A. system, and this did not include stage monitors (which is why you often see photos of singers of that day singing with one finger in an ear so they could hear themselves).
My guess is that, "Ain't That Just Like A Woman?" and "Goin' to the River," the two songs obviously not sung by Alice Cooper are by '50s rebel Gene Vincent, who the Alice Cooper Band, formerly known as The Spiders, often backed up. He played earlier that day.
All this junk does is make money for the bootleggers.
