Great demo, but this is wrong: "The phrase “potato, potahto” comes from a song titled “Let’s Call the Whole Thing Off”, written by George and Ira Gershwin for the 1937 film “Shall We Dance”, starring Fred Astaire and Ginger Rogers. The song humorously highlights regional differences in American English pronunciation. The lyrics go through a series of words with alternate pronunciations, like “tomato, tomahto” and “potato, potahto”. The idea is that, despite these differences, we should move past them, hence the line “let’s call the whole thing off”. Over time, the phrase has been adopted in everyday language to signify a minor disagreement or difference in opinion that isn’t worth arguing about." It's comparing American and British pronunciations, not different regional American ones. Also, "let's call the whole thing off" suggests they should break up over their differences, with the bridge and later choruses then involving a change of heart ("let's call the calling off off").
