I heard this commercial while I wasn't looking at the T.V. and I wasn't sure if it was a really good live halftime thing at the Olympics or what - I don't own or listen to much (any?) Marvin, but this has to be the best version of the Star Spangled.
I recommend it being played instead of whoever is lined up to sing it at the next sports event.
Youtube video of the commercial.
Non-Nike video of the performance.
