I remember singing this song on school outings in southern England in the early 1950s, in the coach coming home. The first part was always about each girl in turn--improvised lyrics such as (I'm just making these up): "There was Mary, Mary, acting quite contrary, in the stores . . ." They were (I think) rather silly and sometimes a bit vulgar. Chorus was: "My eyes are dim, I cannot see, I have not brought my specs with me . . ." And half the girls sang descant on the repeat of the last line.

Thank you for all the amusing lyrics; made our versions seem rather tame now.
