Gotta be "Lizzie Lindsay". When I sing that to my wife Heather, for a few minutes I can picture myself as a noble Scottish Laird. The fact that I'm scared of horses, and would probably cut my finger off with a claymore never enters into it.
Sometimes there is a problem when a public figure (like John Denver) writes a love song at such a young age, to his partner. When the divorce comes, the song becomes kind of an orphan. Maybe we should wait til we're 70 to write 'em.
