The Paul McCartney song "Let 'em In" included mention of The Everly Brothers who were visiting at the time.
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.
Thank you for the wonderful music. Rest easy now.
