The weirdest thing you will see today:
Debbie Reynolds, in full '60s cool, singing "If I Had a Hammer."
This was made by Debbie Reynolds' own production company for the Scopitone video jukeboxes, a '60s craze that didn't survive the decade. I can't find an exact year.
Update: In response to a query, Scopitone expert Bob Orlowsky wrote:
I don't have an exact date, but it was made sometime between the end of 1964 and the first half of 1965. It's great, isn't it?
