Update 2:
I just asked Frank if Scott had to change the lyrics of Berlin's "Sex" since he is not a woman.
"I'm a man - I'm a goddess
I'm a man - Well I'm a virgin
I'm a man - I'm a blue movie
I'm a man - I'm a bitch
I'm a man - I'm a geisha
I'm a man - I'm a little girl
And we make love together"
Frank: I don't think Scott ever sang, I think we just demoed music... it never went anywhere. I think the original idea was for him to do it with Gwen Stefani
