As kids we sang the chorus of Boulton's version with the verses of Stevenson's, using RLS's chorus as the first verse (assuming that 'sing me a song' WAS originally the RLS chorus). They are both to the same tune and would have Over the Sea to Skye as the refrain (I thought it meant reaching the horizon till we went to Scotland for the first time)!

I often wonder what the original lyric was. Possibly a waulkin song in gaelic?

(My song is actually about Long Preston Peggy and the fall of Manchester)
