Billy was a friend of mine
We grew up together ever since we were nine
We went to school, he was my best friend
I thought our friendship would never end

Then we left school and went up to college
He studied medicine and I studied foliage
He made touch-downs, while I played pool
Nobody ever knew which one of us was a fool

Then war broke out and he had to go
But not me, I was mentally unfit
Or so they said, so, so
When he came back, he wasn't quite the same at all
He wasn't the guy I knew
It was like talking to a wall
Yeah-yeah-yeah-yeah

Billy was a friend of mine
Grew up together ever since we were nine
We went to school, he was my best friend
Always thought our friendship would never end

Come on, Billy boy, go, go, go
Billy was a friend of mine
