NO it's NOT a free site..
Try this link: www.musicnotes.com. There are a few things that you may need to install in order to able to download the music, but it should be quick and easy. I'm not sure if it is free or not but you could give it a try. Most of the sites that I found the sheetmusic on seemed to charge a fee, but this is usually small and it may be worth it if you need to music desperately.
