Music for my Opening

I have chosen a song that i think would be perfect for my opening sequence. The song is Brianstorm by Arctic Monkeys. As I know you aren't allowed to used copyrighted songs. The person who is playing the main character in my opening, has agreed to record two separate versions on his guitar of the song in different styles for my opening. I wanted a slow version for the beginning and then the fast one to kick in half way through. The other night we quickly experimented with the slow version and I really liked it! I recorded it on my phone and it has a few mistakes but obviously it's not the final version. Here's a sample of it off my phone for you to listen to.
