One main reason the Manuel Alejandro song is so alive after 40 years is the use in the TV series Montecristo first made in Argentina.
Now after adaptations from Chile, Mexico and Portugal there's a Russian version of the telenovela and they stuck to the same song.
Yo Soy Aquel becomes Ti I Ja and is sung by Alexej Vorobyov. (Алексей Воробьёв - Ты и я)

At Vorobyov's website there's a list of downloadable songs (click АУДИО) and the last one in the list is Yo Soy Aquel.
МонтекристоThe Russian series was cast in Russia and Belarus and received good ratings since the start last summer. The original Argentine series was broadcasted in 45 countries including many CIS states.
Remakes of the series in Spain, Greece, Italy and Turkey are currently in production or negociation, so maybe there will more Yo Soy Aquels to come
Special thanks to Nikolai!
