According to the existing description, this vinheta for Ferroviario has been played by Radio Verdes Mares, the Fortaleza station known as Verdinha, since the 1970s. Verdes Mares became closely associated with local football coverage in Ceara, and short team jingles like this were part of how radio built loyalty before television and streaming dominated. The recording later circulated online through radio history channels, including Enciclopedia do Radio on YouTube, and was cleaned and trimmed with modern editing tools, helping older broadcast audio survive as a shareable soundboard clip today.
