I sing the first line of the second verse "Old mother Hubbard and her dog went Dutch" instead of "were Dutch". "Went" is what I thought I was hearing when I got the song from a Highwoods Stringband recording about 30 years ago. Maybe they sang "were" and I misheard, but I think the idea of Old Mother Hubbard and her dog going Dutch (going on a date in which each person pays his/her own way) adds to the nonsensical humor of the song. Their simply being Dutch adds no such humor.
