Lyrics of 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, 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,
