The song was recorded in the U.S. many times in the 1960's, but I don't recall hearing the "Waly Waly" verse until recently. I think maybe the verse wasn't considered 'marketable' in the '60's. Too foreign-sounding for the time, and it would have been mispronounced "Wally, Wally" in my home in the Midwest.
