By the way, we Yanks use the term Dado too- perhaps a word left over from the Colonial Days. By the way, did you know that the American Congress was within one vote of making German the Official Language of the American Colonies? That would have really influenced "da do run run", not to mention "be bop ba lu bop". We also almost had the Turkey as our national bird, but wisely decided to make it our national meal instead. I think we also use the term "Cowboy Builder", depending on the area of the U.S. Maybe you Brits got that from us?
