歌词：Paul McCartney. Wings Greatest. Let 'em In.

:
Someone's knockin' at the door.
Somebody's ringin' the bell.
Someone's knockin' at the door.
Somebody's ririgin' the bell.
Do me a favor,
Open the door and let 'em in.

Sister suzie, brother john,
Martin luther, phil and don,
Brother michael, auntie gin,
Open the door and let 'em in.

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 favor,
Open the door and let 'em in
