HiWhat about "Red is the rose". It's a beautiful song and has some appropriate lines,
"You choose the road love and I'll make the vow,
and I'll be your true love for ever."
You'll need to change some of it but that should be easily done.
The tune's easy to, if you don't already know it, it is sung to "Loch Lomond"......"You take the high road and I'll take the low road...etc"
