Photographer Richard Upper confirms these pictures were taken in Crestwood Missouri.....

Hey Daniel and Ruby,

This is Richard Upper. I think you may be on to something here. We went to several cities on that
promotional tour for "you really got me". And yes we did go to St Louis as one of the stops.
I reviewed all of the McDonald's in Windsor, Canada and could not find the one we stopped at to take
that picture. I then went to Crestwood and low-and-behold there's the location. I spent a long time verifying that to be true and found too many similarities - even 40 years later- to insist on Windsor any more. Your right, it must be St. Louis! I've had those negatives in the wrong folder for all these years.
You rock Daniel and Ruby, thank you

Richard
