I, too, heard this first from an old 78 Harry Lauder record. Love the song, though I don't know it's history. I would make a slight correction to the words as posted by Tiger: "I've a wee wifey waitin', in her wee bot and ben" is how I learned it. I remember being told that "bot and ben" referred to the kitchen and parlor of a house, but I don't know for sure. Maybe someone can clarify that. Oh, yes and don't forget the final "icht" -- "If you can say, 'It's a braw bricht, moonlicht, nicht... well, you're all richt, ye ken."

Speaking of Harry Lauder reminds me of the story of the overdressed, upper-class matron who approached Lauder after one of his concerts on an American tour. "Oh, Mr. Lauder", she gushed, "I've heard all these stories and I simply must know! Is there anything worn under your kilt?" "Och, noo, ma'am", said Lauder in a confidential tone. "It's all in perrfect worrkin' orrder." (Please pardon the clumsy effort to reproduce his exaggerated "Scottish" accent.)
