Someone knockin' at the door
Somebody ringin' the bell
Someone's knockin' at the door
Somebody's ringin' the bell
Do me a favour, open the door
And let 'em in
Ooh, yeah

Someone's knockin' at the door
Somebody's ringin' the bell
Someone's knockin' at the door
Somebody's ringin' the bell
Do me a favour, open the door
And let 'em in, yeah, let 'em in

Oh, yeah

Someone's knockin' at the door
Somebody's ringin' the bell
Someone's knockin' at the door
Somebody's ringin' the bell
Do me a favour, open the door
And let 'em in
Ooh yeah, yeah, let 'em in now
