That little musical number was specially filmed for television, and went on the air just a few days after the inauguration of television in Brazil. It probably is the ONLY intact attraction that went on the air on Brazilian television in it's first year - 1950 - that still exists.
Other musical numbers were filmed specially for TV, but this is the only known survivor. Not even the innaugural ceremonies were recorded in it's entirety ( I don't understand how and why they could have been so stupidy ). The only moving images of the innaugural transmition are very short and are a part of a newsreel... luckily there was a newsreel crew there shooting pictures of the innauguration of television in Brazil... if they were not there, not even those few seconds of History would be available to be watched today.
