Persistent earworm alert LXXIII

Since last week, the folk tune, "Billy Boy," has run through my mind.  I remember one of my grade school vocal music teachers, Mrs. S., playing the piano and leading the class in singing it.  The lyric that still stands out to me most is, "Can she make a cherry pie, Billy Boy, Billy Boy?" Understandably, a lot of listeners would find that lyric sexist today, so I suspect the song is probably sung in fewer schools than it was in the early '80s.  The melody stays with you, though, after you've sung it.
