Lyrics:

By Paul McCartney

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(repeat)
Sister Suzie, brother John,
Martin Luther, Phil And Don,
Brother Michael, Auntie Gin,
Open the door,let 'em in.
Sister Suzi, brother John,
Martin Luther, Phil and Don,
Uncle Ernie,Auntie Gin
open the door, 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
oo yeah let em in

Sister Suzi, brother John,
Martin Luther, Phil and Don, ooo
Uncle Ernie,Uncle Lin
open the door 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
yeah yeah yeah
