My Favorite Dance Photo

I bought this photo in London in 1978 across the street from Dance Books. I paid another bookseller about $4 for it. I just love seeing Michael Baryshnikov (left) and Rudolf Nureyev (right) hanging out in the parking lot at the old Sadler's Wells. That's my guess anyway. Please let me know if I am wrong! Or, they could be at a tube station, and that looks like a football pitch in the upper left of the photo...
