ClGsP - S01 EP04: Opening of Jornal Nacional on TV Difusora

In Brazil, there are news programmes that are totally national, but did you know that an affiliate of TV Globo already used the name "Jornal Nacional" and made its local version? Well yes, you are not dreaming! The affiliate TV Difusora from Maranhão, before joining SBT, was affiliated with Globo and did just that: a local Jornal Nacional, and that includes its own opening. But, if there are relatively few archives of Brazilian national networks in the 1970s, there are even fewer archives of their affiliates. But there is a portion that helped me solve this mystery.
