This Dutch TV 31 March 2019 video says about itself (translated):
Film crews from all over the world were there: the Bed-In For Peace by John and Yoko. The famous images went all over the world. You would say we have seen them all. But 50 years later, unique images of that moment have come to light again.
This is a report by Tonko Dop.
The 1969 Amsterdam images are unique as they are from when only director Peter Goessens and his cameraman Mat van Hensbergen were still present, and the other film crews were gone.
The Bed-In For Peace was a protest against the Vietnam war.
