I have observed that Observer (always Guest, why not sign up properly) has a habit of jumping on people from a height, and doing down their posts. (Including one or 2 of mine - I await results!) Is that "flaming" or "trolling"? If I've read his or her post of 28th August correctly, he/she has never heard it being sung. But difficult to interpret what exactly is going on here, with so many quotes and re-quotes going on.
But for the record, Guest Observer, the song is still very much alive and kicking, still being sung, by the likes of Danny Couper, Ewan McVicar, Alastair McDonald and other less famous people in plenty of song sessions in Scotland.
