Nino Rota, Henry Léonard - Le Parrain (The Godfather) (Musique Du Film - Music Of The Movie)

This soundtrack is not the original but a reorchestrated version performed by Henri Léonard and his orchestra.

This most likely is an alias for foreign markets, as this album was digitized and auto-added to Youtube in recent years under "The London Pops Orchestra, conducted by Nelson Corbin" from the UK.
