Who's that knocking at my door?

Who's that knockin'? Don't stand outside there, come on in here!
 I just had a sort of feeling this morning
 something good was gonna happen today
 Now there comes a sound without any warning
 I just know it's good luck coming my way!
 Goodness gracious, can it be? Someone's coming back to me
 Who's that knocking at my door?
 I've been waiting oh so long, I'll just die if I'm wrong
 Who's that knocking at my door?
 I know it can't be the mailman, the coal man, the ice man, they've been here today
 can't be the grocer, the butcher, the baker, they don't knock that way
 If my sweetie's there outside, my arms and my heart are open wide
 Who's that knocking at my door?
 Me oh my, my oh me, guess I'm having company
 Who's that knocking at my door?
 See the time? Eight O'Clock. Sounds like a familiar knock
 Who's that knocking at my door?
 I know it can't be the milk man, the gas man, the bread man, who always collects
 I hope that it isn't that butter and egg man, who writes out those checks?
 If it's my sweet used-to-be, gonna lock him in, lose the key
 Who's that knocking at my door?
 Can't be the plumber, the peddler the parlor, cause I've paid those bills
 I hope that it isn't the doctor, the dentist, they can't cure my ills
 If it's someone that I've known, gonna make him feel at home
 Who's that knocking at my door?
 That's all!
