The wisdom of John Lennon
John Lennon, the ex-Beatle shot dead in the streets of New York in December, 1980, left half his wealth calculated at more than GBP150 million and said to be growing by GBP100,000 a day from world-wide record royalties, to his wife Ono, with the other half held on trust for undisclosed beneficiaries.
The will contained a provision that if any named beneficiary "objects or takes court action in any way... then I direct that such legatee or beneficiary shall receive nothing whatsoever."
