Hello People, not been here for a while, hope I'm Forgiven?

Looking for the Lyrics to a song that at some stage was recorded by Billy Connolly and the Dubliners (yes it was done) more likely to be back in Billy's folk singing stage. The jist of the start and chourus goes...

I'm Lying in bed in room 66
Thinking of things that I've done
Like drinking with squaddies
and...................
.........................
These hospital ward is a dreary old place
But The ceilings as much as i see
Could do with a bit of paper and paint
But then again maybe thats me

(Chourus)
Oh sergent is this the exitement you meant
When i put my name down on the line
All your talk of computers, sunshine and Ski's
I'm asking you sergent, where's mine.........

Anyone able to fill the blanks, i think there is about 2 if not 3 or more verses..

Ta Tj
