I am listening to ... and it reminds me of ...
Heatmiser - Big Bad Voodoo Daddy
(the original song was sung on the Christmas cartoon The Year Without A Santa Claus)
Tucker was 3 months old his first Christmas. We listened to this song from our Christmas play list almost every time we got in the car. The kids started making up their own words to it about Tucker.
So the song became Tuckmiser or "Tuckmister".
Fast forward to the Christmas of 2007 and the kids picked up right where they left off. And Tuck would nod along and smile.
Fast forward 1 more year to Christmas 2008. Now Tuck is really into it. And now its HIS song. Its the end of March and he still demands to listen to it after we drop the kids off at school. He insists on listening to "my song." So I put it on and he nods and smiles along.
