I usually modernize/standardize spelling because I hope it will make the lyrics easier for others to find with a search engine. I know I'm not consistent: when I transcribe from a sound recording, I like to record the dialect, if there is any.

In short, I've pondered the problem of whether it's better to use standard spelling or not, and I haven't come to a definite conclusion.

I didn't this time because, being less familiar with Scots, I didn't know how to modernize it, because I didn't know what all the words meant. I admit I didn't even read lyrics in the broadside image. I wish I had—I might have caught the coffer/goffer error. Instead, I assumed "goffer" must be some obscure Scots word I hadn't encountered before!

Just now, it occurred to me that "woo'd" probably means "would" and not "wooed."
