I’ve managed to get a copyright certificate that clears me for use of the 1812 Overture in my student work for assessment and portfolio. It only cost me £7.50 too so not too bad I thought.
If you ever need to look at getting clearance for copyright, check out http://www.prsformusic.com which is where I got mine from. Once you find the right page, it’s very helpful and they can give you a nice certificate that makes you look professional and clears you for use of music. Snazzy.
