From Bill Harry's Facebook:
On John Lennon’s birthday, Elton John sent him a verse: 'Imagine six apartments / It isn't hard to do / One is full of fur coats / The other's full of shoes.'
An older friend, the Beatles' former personal assistant Neil Aspinall, once heard Lennon moaning about the costs of running his business empire. 'Imagine no possessions, John,' Aspinall said. Lennon glared back. 'It's only a bloody song,' he said.
