This is a wonderful Sting tune about making a lifetime commitment in your relationship. I know it isn’t strictly an Irish tune, but it sounds like one so that is good enough for me to play near St. Paddy’s Day. This was recorded at an Irish House concert last year. And ya gotta love my wife’s voice, it still gives me chills. 
Oh, and for those who keep score, the guitar is a Silver Creek T160 (all solid, sitka over mahogany) that Musician’s Friend use to sell as their house brand. The guitar came out of the Recording King factory.
