Not at all, I think thats lovely! Sometimes its not necessarily the meaning of the song but more memories that the song has for you. The song that always makes me think of my grandad is 'Smoke Gets In Your Eyes' by The Platters so I am thinking of asking our wedding singer to maybe learn that for us to dance to! Its a love song but I have lovely memories of listening to it on cassette in the car with my grandad every time we went anywhere!
Its your wedding so do what you want!
As for your OH, tell him to tap into his inner romantic side lol!
