The Tennessee Waltz

The lyrics to the song "The Tennessee Waltz" go like this:

I was dancing with my darling
To the Tennessee Waltz
When an old friend I happened to see
I introduced her to my loved one
And while they were dancing
My friend stole my sweetheart from me.

A sad story which clearly takes place in the past. Possibly the recent past, but the past nonetheless. Now, if the friend stole the sweetheart during the Tennessee Waltz, then how could this song be the Tennessee Waltz? How can the song influence an event in the present (like causing a friend to steal a sweetheart) while simultaneously describing the exact same event which had taken place in the past? This is a self-referential loop that should destroy itself the moment energy is applied to the system, such as when the song is sung. Every performance of The Tennesee Waltz should go "I was dancin- BOOM!"

Don't even get me started on the self referential nature of "Roll Over Beethoven".
