Last night I heard a song on the radio and each verse started with the word 'Completely ..' Completely round.... completely square... completely rectangular.... I wasn't quick enough to get the words down and wondered if this was an old Folk song or just a comedy song. Please help if you can. Thank you very much. If someone has the words and tune I'd be very grateful. I checked the DT but either missed it or it's not there.

Love and Peace to you all.
