Hope this isn't too late, but a VERY good generic song (not just for daddy's) is Wonderful World by Louis Armstrong. I did my father/daughter dance at our wedding to this and my fatehr is 100% country, but like this just the same. Another more generic, but awesome, nostalgia song is Somewhere Over the Rainbow by Israel Kamakawiwo'ole...you've probably heard this already either on ER or on commercials for Toys 'r Us.com or Ivory soap...it's a very nice sounding tenor playing the uke and singing the classic tune. It makes me cry...
