It has been asserted (above) that Land of the Silver Birch and My Paddle's Keen & Bright were originally one and the same song; however, no evidence has been provided. Consequently, those of us who were skeptical remain so. I find it more likely that someone noticed that My Paddle could be added to Silver Birch, and did so, rather than that someone took one verse of Silver Birch and created or found another tune for it.
