I'm trying to find out the name of a song that has a line in it something like (not sure how accurate) "i don't know how much she means to me" or "she doesn't know how much she means to me". It's sung by a guy. Really slow, passionate. An older male singer, voice kind of like Louis Armstrong. Really soulful kind of vibe. And I'm pretty sure the line mentioned above is like a climax of the song.
Sorry for the vague description, I can hear it in my head, and no searches have turned up what I'm looking for yet :-(
I think there is a line like that in a Johnnie Cash number, but can't grasp it at the moment. Have you seen the great biographical movie 'Walk the Line' ? -Think it's in there somewhere.
