It's kind of ironic that one of the last of John Lennon's songs was this lovely ballad, "Grow Old Along With Me" in which he prays "God bless our love." This is the same guy who wrote the anti-religion "Imagine". One hopes John was able to work it all out with his maker at some point. That said, Grow Old is a very beautiful song. This version is by Mary Chapin Carpenter. The only versions we of of Lennon singing it, are some home recordings which suffer a little from the poorer quality of home recording equipment of the day.
This is a beautiful song. Perfect for weddings. It's sad that Lennon was looking forward to growing old along with his wife and died very soon after he wrote it.
