The Green Hornet Theme is a very fast piece that was originally written for trumpet. I think it must be near impossible on trumpet but it's actually not that difficult on guitar, though it still requires some fast picking. It's a great exercise for learning speed picking.
 
There is a video of me playing this arrangement on Youtube if you want a reference for how it sounds on guitar.
 
It was originally performed by Al Hirt on trumpet.
