Well we both remembered the 'Road' bit! :)

I would say that his sexuality is part of the plot - the opening song has a male character going 'I was the one you fucked' to him - and that he's prepared to go for the money (seduced by his brother's play-long obsession?) over that relationship.

I'd be surprised if it had as much as half the budget of Pacific Overtures - a quarter to a third would be my guess.

That's not convincing me to see more of Black Doves...
