 Three Beatles sue Allen Klein

Unhappy with the past business management practices by Allen Klein, John, George and Ringo decide on legal proceedings against their former manager. According to Allen J. Wiener, author of "The Beatles - The Ultimate Recording Guide" wrote that the three Beatles "fired Allen Klein and sued ABKCO (his company) in High Court over payments due The Beatles. Klein then countersued for $19 million claiming that he was due unpaid fees. When the suits were settled on Jan 10, 1977, Klein paid The Beatles $800,000 and The Beatles paid ABKCO between $1 million and $5 million. Klein had also sued Paul for $34 million, but that suit was thrown out of court. Klein was later sentenced in New York to two months in prison and a $5,000 fine for tax offences. Klein's approaching departure from Apple ushered in a period of renewed goodwill among The Beatles."
