“Let ‘Em In” is a song that has taken its share of abuse over the years on both sides of the Atlantic. The second single released off of Wings at the Speed of Sound, it reached # 2 in the UK and # 3 in the U.S. in 1976.
The song puts forth a litany of people. “Sister Suzy” is a reference to Linda McCartney, who played Suzy in “Suzy and the Red Stripes”. “Martin Luther” believe it or not is neither Martin Luther nor Martin Luther King, but rather an old nickname for John Lennon, as the other three Beatles used to jokingly refer to him as “John Martin Luther Lennon”; “Brother John” is Linda’s brother, attorney John Eastman, who also looked after Paul’s business interests; “Phil and Don” was an obvious reference to the Everly Brothers. “Auntie Gin” was Paul’s beloved Auntie Gin, who was responsible for hooking up his parents. “Brother Michael” is obviously Mike McCartney, Paul’s younger brother and former lead singer of The Scaffold.
However, in a later verse, Paul eliminates “Brother Michael” and instead says “Uncle Ernie”. Uncle Ernie is a reference to Paul’s good friend, Who drummer Keith Moon. Moon played the character Uncle Ernie in the 1975 film version of the rock opera Tommy.
A well known anecdote is that after Moon listened to the 1973 Wings album Band on the Run, he immediately rang up his friend Paul to inquire as to who was the great drummer on the tracks. Moon was astonished when Paul told him that Paul himself had to handle the drumming chores because original Wings drummer Denny Seiwell quit at the last minute.
Ironically, Keith Moon and his girlfriend dined with Paul and Linda McCartney on the night that Moon died, September 6, 1978. After dinner, the two couples attended a London preview of the film The Buddy Holly Story. Afterwards, Moon returned to his flat he was renting at 12 Curzon Place in London and took way too many Heminevrin pills, which he had been taking to prevent him from drinking alcohol. He compounded the situation by eating food immediately afterwards. This combination caused him to die of an overdose.
Moon died in the same flat and the same room in which Cass Elliot of The Mamas and the Papas had died in 1974. The owner of the flat was Harry Nilsson. Nilsson would lend the flat to friends when he was out of England. Naturally, when these two famous artists died in his flat, many eerie urban legends abounded about “Harry Nilsson’s Death Flat”. Contrary to some of these bogus legends, Nilsson did not die in this flat when he perished from a heart attack in 1994 in California.
