Q: did you have to sit down and think about "on in up at or so / by if to of no it" or were those lyrics prepackaged with the melody?
A: given the line that came before, that was somewhat of a logic puzzle. Also it is worth mentioning that the melody was already established before, because it's the same as the other verses. And in this rare case, the melody was already established way before the song was even written, because this melody figure came to me in a dream with no lyrics on it
