You picked a good one, Brett! My sister is a member of the A.C.Doyle Soceity of America, so I know all this stuff. Yes, the poem is original, written by Doyle. I have attempted several times to write a tune for it, but have always found the tune of the Act III finale of "La Boheme" -- 'The Tattoo' works best. The other Doyle-penned poem in the book, "The Franklin's Maid", I put to music several years ago.Lol...sometime me and my sister just start singing "The Song of The Bow" (as it is known) for no apparent reason, much to the puzzlement of others!
