If you think it's a bit too long, I think that the first phrase
"Happy birthday to you" would be sufficient and will fit on one staff:

                    Ha - ppy Birth - day      to         You.  ...


This would be how I play it.......I throw a little heavy distortion
into sometimes for the hell of it.


Happy birthday 
(time it how you want to)
