Other samples in the song include:

“When will you die?” played backwards, from Morrissey’s “Margaret on the Guillotine”

“This is my suit and my shirt… That’s my suit and several shirts… I must never be mutton dressed as lamb”, Margaret Thatcher, from an interview with the BBC2 show Forty Minutes (see transcript)

“It’s another true story”, from Radio 1 show Steve Wright in the Afternoon

Fragments from news broadcasts:
“In a letter to a Tory MP, the Prime Minister says that if a person could reasonably spend some of the savings, they couldn’t be excluded from other benefits if they then had less than six thousand tucked away…”
“England are on the brink of victory…”
“The Prime Minister has again attacked…”
“Mrs Thatcher is said to be sad to hear about…”
“Mrs Thatcher saw them in the morning at the House of Commons…”
“Neil Kinnock departs for Newcastle tomorrow to visit the Jelly Tots factory”

The song closes with a sample from the 1972 film Cabaret: “The morning will come / When the world is mine / Tomorrow belongs / Tomorrow belongs / Tomorrow belongs to me”
