I'm with you, Bill. If I can modernize a song without mutilating it, I do. Take a song by Burns, for example. I figure that if Robert Burns miraculously came to my house, I wouldn't make him talk like me. So why should he make me talk like him?

And so, for example, I feel free to change "ilka" to "every" and "a'" to "all." The purpose of language is to communicate, after all.
