Not Waving, But Drowning Songtext

I read about a man getting drowned once
His friends thought he was waving to them from the sea
But really, he was drowning
And then I thought, that in a way
It is true of life too
That a lot of people pretend, out of bravery really
That they are very jolly and ordinary sort of chaps
But really, they do not feel at home at all in the world
Or able to make friends easily
So then they joke a lot and laugh
