A copy of the contract which finally broke up The Beatles is expected to sell for $50,000 when it hits the block at Sotheby’s next week.

The contract, signed by all four band members in 1974, officially dissolved the band’s Apple Corps Ltd business and broke the last legal ties that were binding them together.

Ten days later, whilst on holiday at Disneyworld with his son Julian and his then-partner May Pang, a lawyer finally caught up with him and handed him the decisive document.

Pang later recalled the moment Lennon signed the contract:
