Hey! Way back in the day I once worked at Disneyland when Jan & Dean performed on the quaint little Plaza Pavilion stage. Even spoke with them between shows. (True story.)
I'm almost certain I remember seeing them using this camera! (Veracity is left as an excercise for the student.)
[Edit: Yes, Jan Berry in 1966, I believe. Serious head injuries. The intimate Disneyland performance in the mid-70s was, IIRC, an "off-Broadway" tune-up for their eventual return to live performances. The out-of-the-way place was so packed with Park employees that none of the guests could even get close. 7000+ employees mysteriously all took their lunch breaks at the same time...
And I swear I saw this camera that night!]
