It is alledged that McCartney said that Yoko was interested in him before she hooked up with John Lennon. Could that have started all this feuding? The rift centers around the wording of the credits for Lennon and McCartney's songs. Yoko claims that the two agreed way back when that the credit would be labeled as Lennon/McCartney. McCartney disputes this and on his "Back in the U.S." album the credits read "Paul McCartney and John Lennon". Ono's lawyer commented on this saying that this was "absolutely inappropriate".
