Because for me, '60s pop music is amongst the most complicated or complex music because it has so many resonances which strike you. The music itself is often simple, but the way that I interpret it, or the way I think it's interpreted culturally, is very complex.
In the industry, you do need some ethics - if one film does well, then thousands get work and money comes back to the industry. I guess the bottomline is, if there are two versions, then the better one will click.
