"Mashed Potatoes U.S.A." is a rhythm and blues song by James Brown and his Famous Flames.
[1] The title refers to the Mashed Potato dance popular at the time.
The song is a travelogue set over a strummed guitar/organ riff with a muted trumpet providing a jazz counterpoint to the vocal delivery.
In the song, Brown asserts "Here I am and I'm back again," then states his plan to bring the mashed potatoes to the cities he will tour.
He then name checks his itinerary, starting with New York City and ending with his home town, Augusta, Georgia.
