TAPS- the destroyer of a good night's sleep

It's thursday night and I'm lying in my bed, trying to fall asleep. As I try to quiet my restless mind, a song begins playing in my head. It was TAPS. Then I asked myself, "I wonder what the solfege is to that song?" So I began to figure it out. At first I thought it was Do Fa- Do Fa La- Do Fa La- Do Fa La- Do Fa La- Fa La Do- Do La Do- Do Do Fa

Then I thought that an entire song based entirely around the four chord would be kind of odd. So this is what I changed it to:

So Do- So Do Mi- So Do Mi- So Do Mi- So Do Mi- Do Mi So- So Mi So- So So Do

I suppose that both ideas are possible, but I find the latter more believable.
