Jack is correct in as much as the Thistle of Scotland, posted lyrics, does not appear in any edition of the Rebel Ceilidh Song Book.
The link is to a Scotsindependent web page which has confused the gaelic song Foghnan Na H-Alba, translated as the Badge of Scotland, which does appear in the Rebel Ceilidh S/B. However 'fothanna' is Gaelic for thistle. So the English title for the song sung by Donald Campbell printed in the Rebel Ceilidh Song Book is The Thistle of Scotland but an entirely different song as that posted above.
