Will the Sec said:DP arranged a Double Violin Concerto with 10 Piece accompaniment. (Can't remember the composer.)
If you ask him nicely. he might let you borrow it...
Bach was the composer ('twas only the first movement, though. Rest of it has since been done!) but willing to let you borrow it. If and when I get my brass publishing business, I'll be charging for it so how's that for a plug? Get it free while you can! ;-)
