Lời bài hát: Paul McCartney. Wingspan (Hits and History). 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
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.
