 A hotel manager called Moon in his room and asked him to lower the volume on his cassette recorder because it made " too much noise . " In response the drummer asked him up to his room , excused himself to go the bathroom , put a lit stick of dynamite in the toilet and shut the bathroom door . Upon returning , he asked the manager to stay for a moment , as he wanted to explain something . Following the explosion , Moon turned the recorder back on and said , " That , dear boy , was noise . This is the ' Oo . "
