I could look for 'Bedpans Away', but I suspect he's past that. Maybe he should have his own shanty.

I bid farewell to the pretty young nurse
Way, hey, blow the ball up
I saw who was comin' and stifled a curse
One more damned time to blow the ball up

I really hoped I'd be restin' my eyes
Way, hey, blow the ball up
The therapist says "time for your excercise"
One more damned time to blow the ball up

Inhale then exhale so steady and slow
Way, hey, blow the ball up
Make it stay at the line, not above or below
One more damned time to blow the ball up

Blow the ball up, Tommy, blow the ball up
Way, hey, blow the ball up
Don't get confused and, by mistake, suck
One more damned time to blow the ball up

Will go see him whenever he's moved and would like visitors.
