Well, these shouldn't be considered serious attempts to re-write the ending of a song - more like a commentary.

While I love the songs, I don't much care for romanticizing the "died for love" stuff in some of them. I also happen to like happy endings. (Or at least sarcastic comments about tragic endings.)

ANNACHIE GORDON
The day she was to marry was the day that Jeannie left
She split with young Annachie, and her parents were bereft
And Lord Saltoun was surpris-ed, he was without a clue
But Jeannie's sister had the hots for him, and they hit the highway too

So you who have a daughter, don't meddle in her life
For she may, just to spite you, decide to change her life
And run off with a sailor, beggarman or tinker
And you will rue the day you didn't get to know the stinker
So the lives of all but Mum and Dad were filled with light and laugher
Since the couple wed in London town and lived happily ever after

BARBARA ALLEN
(after the rose-grew-out-of-their-dead-bodies verse)

Two young people died that day
Neither one the wiser
But although their love was not to be
They made good fertilizer
