For a time after the Beatles' contentious break-up, George Harrison was the most popular and successful of the former group. His November 1970 three-disc set, "All Things Must Pass", was a sales triumph, and produced hit singles in "My Sweet Lord" and "What Is Life". In the spring of 1971, Harrison learned from his friend and mentor, Ravi Shankar, about the desperate people of Bangladesh, who had been devastated both by military violence and a vicious cyclone. Harrison immediately set about organizing an event which would take place in Madison Square Garden within just five weeks—the Concert for Bangladesh—from which a live album could raise further funds for the Bangladeshi refugees. Klein hustled to get the invited artists, including Bob Dylan and Eric Clapton, to play for free while donating their shares of royalties to charity, and convinced Capitol Records to grant an unprecedented 50% royalty rate. The "Concert for Bangladesh" live album and film raised over $15 million. Klein had failed to register the shows as a UNICEF charity event, however; as a result, the proceeds were denied tax-exempt status in Britain and the US. The IRS attempted to tax the income, and $10 million of that amount was held back for years.
