I want to know the answer to the following question:
When did John Lennon return his MBE insignia?
All the background I'm provided with is that "John Lennon justified the comparative merits of his investiture by comparing military membership in the Order: "Lots of people who complained about us receiving the MBE [status] received theirs for heroism in the war – for killing people…". Is that enough to answer the question?
Answer: no
