When my oldest got married it was down to two songs for the dance, Daddy's Little Girl by the Mills Brothers or I loved Her First by Blake Shelton. I settled on The Mills Brothers, it fit me better.
For the Parents dance, we did Micheal Martin Murphy's, What;s Forever For. Between us and the in-laws we had almost 80 years of marriage between us. We were at 32 years and they were 35.
