Pino Donaggio as well as composing the score, performed a substantial portion of it himself. He played the piano pieces, despite the fact that he was not very accomplished at playing the piano. Donaggio claims that since he was not very good at playing the piano, the pieces had an unsure style to them, perfect for the effect they were trying to capture. The song - "I Colori Di Dicembere" - was recorded by Iva Zanicchi and released on her 1974 album "Amare, Non Amare". It is not heard in the film and was only included on the Italian pressing of the soundtrack where it was released as "A Venezia... Un Dicembre Rosso Shocking". This new edition of Donaggio's classic score reinstates the song and reverts to the original track sequence and edit.
