The Birthday song

This song is something that I put together for a friend's birthday. It is not published because it contains the universally known "Happy Birthday" lyrics and music within itself. In fact, the whole song has that chord structure but I tried to hide the simple "Happy Birthday" song from you until I was ready to spring it on you half way through when you are supposed to be thinking it is something else altogether. To help hide it, I start the song with a few bars of completely different chords - to throw you off. In other versions than the one here, I close the song with those chords as well. They are: Fm7   A#7   G7 setting up C to go...

I have made three versions of the song, tailoring the words and, this time... the tone of the music for the person having the birthday. This version is the third version I did and it is for my Lady, Giselle.

And, I won't explain the ending, except... huh, why not!?
