If this is the song that goes:-

Completely round is the perfect pearl the oyster manufactures
Completely round is the steering wheel that leads to compound fractures
Completely round is the golden fruit that hangs in the orange tree
Yes the circle shape is quite renowned
And, sad to say, it can be found
In the dirty low-down runaround
My true love gave to me, yes my true love gave to me

I learnt it off a recording by Blossom Dearie which was taped and sent to me by a friend.
