Talk:Rede Tupi (Brazil)
I found the final Rede Tupi logo in a higher quality, and it's a special variant used in the final Seconds of the network!
The music playing in the background is "Victory at Sea", by Richard Rodgers. There's also a noticeable Static sound in the background before the broadcast is shutdown.
