ARCHER's Little Corner

Ring-a-ring-a-rosies A pocket full of posies A tissue, a tissue We all fall down The king has sent his daughter To fetch a pail of water A tissue, a tissue We all fall down The robin on the steeple Is singing to the people A tissue, a tissue We all fall down The wedding bells are ringing The boys and girls are singing A tissue, a tissue We all fall down
