The bricklayer's son goes dit-da-dooThe bricklayer's son goes dit-da-dooThe bricklayer's son goes dit-da-dooThe bricklayer's son goes dit-da-doo
Occasionally additional verses were added in which the bricklayer's son "went" various other nonsense syllables such as "raw-de-raw," but usually it was just "dit-da-doo." There was also a variant that replaced the fourth line with "All day tomorrow," but that was considered uncool and was only sung by girls.
The thing is, it seems as if the song must have been around for a while, since referring to anyone as "the bricklayer's son" isn't the sort of thing that would come naturally to American children in the late eighties, but I can find no reference to it anywhere on the Internet. So I'm remedying that by posting it here, in the vague hope that years down the line someone else will google the line, end up here, and leave a comment saying, "You remember that, too? I thought I was the only one!"
