Sometimes I think I don't know what I'm doing,
But I always end up doing what I know,

Sometimes I think I don't know what I'm doing,
But I always end up doing what I know,

And It's amazing when you think of it,
How many people smoke,
Despite the risks that are involved,
There's really very little hope, -
Without them we just couldn't cope,
Couldn't cope, neither could we

Sometimes I think I don't know what I'm doing,
But I always end up doing what I know,

Doing what I know, doing what I know
Sometimes I think I don't know what I'm doing,
But I always end up doing what I know,
Sometimes I think I don't know what I'm doing,
But I always end up doing what I know,

Have you ever wondered,
What would happen in a third world war,
No sooner would it have begun,
Than it would be all over,
Just look over your shoulder, your shoulder,
It's above your knees

Sometimes I think I don't know what I'm doing,
But I always end up doing what I know,

And what I know, may not I know be a great deal
But what I know nobody can take,
Nobody can take, nobody can take away from me,
No, no, no, awav from me, no, no, no
I do what I know, doing what I know

Sometimes I think I don't know what I'm doing,
But I always end up doing what I know,

Away we go doing what I know
