This is a video of a woman "singing" the vocals on Afterlife's 'Avenged Sevenfold' in Rock Band 2 on expert with a flute. I've known you could do this for awhile because all that matters is that you hit the right pitch. WHICH, TEAM, IS EXACTLY HOW YOU HIT HOME RUNS. Now get out there and make coach-y proud, I'm betting on you.
Thanks to collin, ROCKY, bubbler and DJ JD, who have all tried the same thing with saxophones and failed miserably.
