Practicing TTFATF

I’ve been practicing Through the Fire and the Flames on Expert lately on GHIII on my X-Box 360. I’m still having alot of trouble getting the intro nailed down, my fingers just can’t seem to move fast enough. Once, I taped down the green button and made it through the intro only to fail 89% of the way through the song… <.< I know the tape is cheating but I’d like to be able to complete it at least once :P
