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, away 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,
