I Love Football

So I made up a song for Brax to help with letters and sounds.  It goes along to the song, Freres Jacques.  One example:

I love football
I love football
Yes, I do
Yes, I do
F is for football
ffff, ffff, ffff
ffff, ffff, ffff

Brax shouts out what word he wants next in the song.  He likes football, basketball, volleyball, snack, names of people, and other random words.  Here is a video of him singing our song.  He was stuck on the first part of the song.
