I could have sworn the concert you have listed as 1 July 1970 was actually in 1971. Staple singers opened for the Who. I had front row seats. Pete had all sorts of equipment problems that night.
I think the Who were booked at the A.T.
July 1st.,2nd. and 4th. 1971. The concert listed as 17 August 1971 was in 1970.
I’m not sure about the July 1st, 1970 show. But the August show is not from 1970, because of the setlist. It’s typically 1971 stuff. Any help is welcome.
