I listened to a number of recordings, and it seems to me that Mrs. Duck has the lyrics that are closest to what's sung. I didn't hear a single recording with "somebody waits for me," but that's what most people have posted. I found a recording by Rick Kemp, John Kirkpatrick, and Ian Kellet. One would think those lyrics should be definitive....and those are almost exactly the lyrics on the Kemp/Kirkpatrick/Kellet recording.
I think Maddy Prior departs in one place and sings "Raise your eyes and see my world," but I might be hearing her wrong. Whatever the case, I like the Maddy Prior and the Silly Sisters recordings best. Who's singing lead on the Silly Sisters recording?
