Sir Paul McCartney says Yoko Ono for a time earned more than he did from his classic Yesterday.
Although credited like most Beatles songs to Lennon and McCartney, he crafted the song alone and the recorded version featured none of the other Beatles.
But he told Radio Times that the deal he signed in the group's infancy, and to which he is still tied, means he gets a small cut of the proceeds.
"John and I were 20 when we signed our first agreement in a dark flat in Liverpool, which still applies to this day.
"And many bosses later - most recently Michael Jackson and Sony - we still haven't had a raise."
"Luckily I've done so well I don't feel bitter, but it's pretty terrible and wrong. They should recognise our success and alter the deal.
"At one point Yoko earned more from Yesterday than I did. It doesn't compute, especially when it's the only song that none of The Beatles had anything to do with.
"I asked as a favour if I could have my name before John's on the Anthology credits for Yesterday, and Yoko refused."
But he says life is too short to keep pursuing the matter with her.
Peace, ;heart; and Beatles,
Beatle Me This, Beatle Me That
