Andreas, I remember something like that, but mostly nonsense words. "Eve-er I-ver O-ver Rue, something something I pick you". It was one of those choosing rhymes. Like "Ein, Zwei, Drei, horsengoggles."
And Frank, there is a never-ending round to that rhyme, goes,
Fuzzy-wuzzy was a bear,
Fuzzy wuzzy had no hair
Fuzzy-wuzzy wasn't fuzzy, was he?
was a bear,

Blessings,
