Oh, you’re asking about the line “Oh, where have you been, Billy Boy, Billy Boy?” and related references. Here’s a concise guide to who or what this line refers to in its most common contexts. Direct answer

• The line is a well-known opening of the traditional English folk song often titled Billy Boy or My Boy Billy. It’s heard in various folk-song collections and has many regional lyric variations. In its core, it’s a call-and-response format about a young man named Billy (often called “Charming Billy”) who has been out seeking a wife, with the reply highlighting a young love who cannot leave her mother. This reframing appears in multiple sources as a variant of the broad ballad tradition, with Vaughan Williams notably collecting and publishing related versions in the early 20th century.
