This English folk song goes back at least to the 1600's, but it is still sung and played today as an easy piano piece, as part of an opera by Benjamin Britten, and--maybe most popularly--in the 2015 film, Cinderella. The version you are getting in First Pieces has eighth notes--you know, the ones connected by a big bold line--which mean play twice as fast as the previous quarter notes. Resist the temptation to pause after this series of faster notes. The last one is also short which means the G after the bar line needs to come in quickly.
