Song title IN the movie

Rating: Null/10 (15 October 2006)

There is a recurrent aria used in the movie, sang by a male voice. It is played at the beginning, middle and end of the film. If anyone knows where it's from, I'd totally appreciate it. It is not the one in the DVD menu section, by the way. I would also like to note that Scarlett Johhansen looks fantastic in this film. It sure has been awhile since I saw a Woody Allen picture and this one got me urging for more of his work. I also found it odd that he would choose (Allen) London, rather than his ever faithful NYC. I tried looking up the soundtrack for this movie all over, but I am so far, unsuccessful. Once again, if anyone knows about this piece, please post here.
