Lulu: I don't know all that much Harlow, other than the two movies made about her. Six symbol-wise, I like most Marilyn films, especially Some Like it Hot and The Seven Year Itch.
When I do arrangements of songs, I either sit at the piano and figure them out (like intros and rideouts and the layout of the song) or I sit with the musical director and hum what I hear and he notates it. My favorite story (which I've told here before) is figuring out the "flying ballet" section of I'm Flying/You Can Fly on my Peter Pan album - it came to me full blown while walking down Broadway and I called Todd Ellison from a pay phone and hummed the whole thing onto his answering machine, complete with all the "quotes" from other flying songs (ET, Can You Read My Mind, etc.). It was hilarious.
