A YouTube user by the name of "Smooth McGroove" has recently uploaded his acapella version of the fight theme from the NES video game "Mike Tyson's Punch-Out!!"

McGroove's even provided video showing himself voicing all the parts, "Brady Bunch" style, in case you didn't believe him:

"Punch-Out!!" is just the latest of 80 old-school video game theme songs the Oklahoma-based McGroove has covered.

Check out this one from "Street Fighter 2."

And here's the vocal stylist's take on "Mario World."
