The "Mashed Potato" was an early '60s dance craze. As a result, there were many songs around this time that used some version of "Mash" in the title. Examples include "(Do the) Mashed Potatoes" by James Brown, "Monster Mash
" by Bobby "Boris" Pickett, "Mashed Potato Limbo" by Chubby Checker, "Mashed Potato Party" by Link Wray and "Mashed Potato Twist" by B.B. King.
