Okay, now this is why that song is so special. It's not about a terrible breakup or divorce. It's about his battle with Alzheimer's. He wrote this song for his wife and kids and this is the last thing he was able to record. Listen to it again.
I've never been a fan of country music, but my mom & dad listened to Glen a lot while I was growing up and I think this song - if the fates are just - will be loved as much as Johnny Cash's rendition of "Hurt". It has the same strength and pain in equal measures and is just a glorious way to end a magnificent career.
