If it's any help it's almost exactly the same horn arrangement used for Roxy Music's "Get together". It may sound weird 'cos I don't think either group used trombones particularly. The whole thing should sound a bit sharp. Dare I say it, almost 'mariachi' ( and I know I didn't spell that right ).

The whole thing does hang on the arrangement though, it's hard to tell without a score.

( This sort of thing being the one thing I liked to play when I played trumpet, not neccesarily very well )
