Part of the problem with finding this song is that everybody insists on spelling it differently, but the very useful "Digitrad and Forum Search" facilty on the Main Forum Page, when asked to find for charlie, returns:
When there is any doubt about spelling (almost always the case when dealing with Scottish songs, which are often a combination of Standard and other spellings, and which in any case many people misunderstand) a search for a phrase is far more likely to succeed than a search for the title.
