It takes a certain amount of confidence to be a solo musician, but what if you are a whole band and still solo? That, we would think, takes even more confidence. Or does it take less because you have a whole bunch of "you's" backing you up? Well, YouTube user csvy attempts to answer that with his awesome, solo, acapella rendition of the Super Mario Brothers theme. Please note, he also looks a lot like the chef from the animated movie Ratatouille. See for yourself and admire his vocal stylings.
I would say that is worthy of an extra guy.
