 In 1976, Klein and Bennett were each charged with three felony counts of attempted income tax evasion for 1970, 1971 and 1972, as well as related misdemeanor counts of making false statements on their income tax returns for those years.The IRS claimed that Klein and Bennett had sold promotional copies of Beatles and post-Beatles albums, including "The Concert for Bangladesh", without declaring the sales on their tax returns.Having resigned from ABKCO in late 1975, Bennett pleaded guilty to a single misdemeanor charge and then became a key witness for the IRS in its case against Klein.
