It really bothered me that there are no notes on the music in this release, so I have created some using publically available sources (trust me I am no expert on the music of Malcolm Arnold!). I have learned a lot about these pieces by doing so, and I would be happy to email them to anyone who wants them. There is a bio of Arnold, something written by him on music and his approach to it, and short descriptions of each piece.
I was disappointed that there wasn't a lot of info on Arnold's official site, but it didn't take too long to find some other sources.
