According to friend of this blog, The Gilly, (which is the best inactive blog on tumblr. She no longer updates it, but there is a load of great photos and information to be found there):
This… is a picture taken by a lady called Manny Klimis, who was vacationing with a cousin who had got some work on Help! as an extra. I know it’s hard to see, but it is actually John Lennon “apparently high on marijuana, recklessly scaling the floodlights at the grounds of the Bahamas Softball Association.”
The scenes where the Beatles were running around searching for Ringo were filmed 50 years ago today, March 5, 1965.
