When Nick was little, we would sit on the porch and I would sing a medley of songs for him including "I've been working on the Railroad", "Boom,Boom, Ain't It Great to be Crazy", and "My Gal's A Corker". We loved those songs, but not sure if they'd work at the reception. I'm getting lots of good suggestions and I will check them all out. Thanks to everyone for your help.
