My parents have a slide of the Osmonds taken at Disneyland. They were on a double decker bus near that circular area behind the Main Street railroad station -- all looking down and wearing the same exact clothes as are in this video.
This is why I Laugh when ever I see so called high-tech humanoid robots today. The Disney "Imagineers" were doing facial animatronics ..etc way back in the 60's.
It was a special aired on Disney's Wonder World of Color, which was a TV show aired in the late 60s to mid 70s on NBC (American Network). The episode was called "Disneyland Showtime" and it aired in 1970.
