Found another image from the 1970's - Todd Rundgren in Central Park at Summer Stage.
Summer Stage was one of the fun New York venues every summer in Central Park. For some reason there was a large mirror that hung on the downstage end tilted down in toward the muscisians. Not quite sure but perhaps this had something to do with lighting the artists as we were still in the early days of the technical enhancements we have today.
At any rate you can see this photographer standing in the back in a black t-shirt and jeans. Note the Pentax one degree spot meter hanging from my neck - great for determining a zone system exposure. I also counted no less then three other photographers walking around the stage - something that would never happen today.
I always said that back in the day one could never tell the artists from the audience and crew...
