Who can it be knocking at my door?   Go 'way, don't come 'round here no more   Can't you see that it's late at night?   I'm very tired and I'm not feeling right      All I wish is to be alone   Stay away, don't you invade my home   Best off if you hang outside   Don't come in, I'll only run and hide      Who can it be now?   Who can it be now?   Who can it be now?   Who can it be now?      Who can it be knocking at my door?   Make no sound, tip-toe across the floor   If he hears, he'll knock all day   I'll be trapped and here I'll have to stay      I've done no harm, I keep to myself   There's nothing wrong with my state of mental health   I like it here with my childhood friend   Here they come, those feelings again      Who can it be now?   Who can it be now?   Who can it be now?   Who can it be now?      Is it the man come to take me away?   Why do they follow me?   It's not the future that I can see   It's just my fantasy      Oh, who can it be now?   Who can it be now?   Who can it be now?   Who can it be now?      Oh, who can it be now?   Oh, yeah, who can it, who can it   Oh, who can it be now?   Oh, yeah, yeah, yeah
