Updates on movie for our trailer

We was going to get Steph's dad to play us a piece of music but after serious consideration of equipment issues and sound quality we decided to use Beethoven's Fur Elise as mentioned before this went well with our trailer. However, we were aware that we needed permission to use this, on purchasing this piece of music, a document arose stating that we may use this piece as it is over 50 years old and we are not actually using this project that we are creating in order to make money.
