This is a great song that I've never heard before this thread. When I saw the titleof the thread, I figured that Todd must have covered Hank Williams' song I Saw The Light, but I discovered a brand new super song when I came to the thread.
While melodies and lyrics can be copyrighted, chord progressions and titles cannot, so there are often more than one song with the same title. At my Aunt Vera's 100th birthday party, she asked the piano player to play her favourite song, the one my Uncle George used to sing to her when they were courting, Have I Told You Lately That I Love You. He played and sang the Van Morrison song with that title. Vera turned and whispered to my wife Maggie, "That was a nice song, but it's not the one George used to sing to me."
We later played the Scotty Wiseman song called Have I Told You Lately That I Love You and she said, "That's the one!"
