Father- Bride Dance

I’m having a very hard time choosing a song for my dad and I. My mother passed away a year and a half ago, and prior, I was super close to her emotionally, not so much my dad. This loss has since brought my father and I much closer, and we have always had a great relationship, but he was never really emotionally available. All the “Daddy's little girl” type vibes never quite fit us. I get very emotional with song lyrics and want them to feel right and not awkward. I was thinking of doing a song in honor of my mom, but my father has a new gf that will be there (she’s very nice and good for him) and I know I would cry buckets and want to keep the day light. Any song suggestions?
