"Doing What I Know" by Gilbert O'Sullivan

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,
