For those of you that are regulars at the Sturgis Bike Rally in South Dakota, you should remember this date in 2009 when Aerosmith frontman Steven Tyler fell off a catwalk during the Aerosmith performance.  He had some pretty serious injuries including  a broken shoulder and had to be airlifted to the hospital ... is it comin' back to 'ya now..?   His injuries unfortunately forced Aerosmith to cancel the remaining dates on their tour!  I'm guessing he's never tried the catwalk again since ...
