For some, you just "pucker up and blow," for others you "whistle down the wind," but for Alessandro Alessandroni, whistling is more than a way to expel tuneful air. Whistling in the movies may not have been well covered by the cineaste press, but the elegant 79-year-old Italian could be the possessor of the most famous whistle in film history. His pursed lips were responsible for the whistle work on Ennio Morricone's haunting theme to Sergio Leone's "The Good, the Bad and the Ugly." "I didn't know my whistle was so good, so right, so tuned," he said. "I was working with (composer) Nino Rota on 'Il Padrino' (The Godfather), and at the end of the session, he asked the orchestra if there was anybody who could do a small whistle for a soundtrack. As nobody answered, I said, 'Maestro, I can try.' " It was done straight-away with no whetting of the whistle. "A perfectionist is supposed to read just once and then play or whistle. It was one take," he remembered. His performance was so successful he went on to lay down the whistling on movies like "Trinity Goes East," compose for scores of movies and record a stack of albums. Just as well, as his performance on "The Good, the Bad and the Ugly" earned him the princely sum of 50,000 lire, about $40, in total. Now repped by Gulp Music, he is in Cannes to meet music publishers and further his career as a composer, trying to secure everything from new film scores to ring tones. He is set to write the soundtrack for a movie called "Rule 11" and has recently collaborated on a single in Germany and worked with the London band Audio Bullys. Still heavily involved in concerts, he is as busy as he has ever been. "It's amazing," he says. "The music publishers want my music; it's like having my career all over again." (Sam Andrews)
