dsnito, I believe the rumor about George bagging Maureen got infamous exposure from Apple insider Peter Brown's book, The Love You Make.
On the other side of the coin, Apple insider Ken Mansfield also published his view of things in The Beatles, The Bible and Bodega Bay. If you haven't read it, it is an unusual book. In between chapters on his experiences with the Beatles, he places chapters containing his current Christian life. At any rate, I found it to be worth the read, the Beatle stuff was very interesting.
His comments on Peter Brown:"I was very disappointed in the slant he took in his book, The Love You Make. I was in the room during different instances he wrote about...I found I greatly questioned the other stories in his book where I wasn't present. My greatest objection was to the dark-side approach he took to events and the Beatles themselves. I think there must have been two John Lennons---I never met his!"
I suppose it's safe to conclude that the truth lies somewhere between these two insiders. Who's gonna really know? Everybody has a skeleton hiding somewhere. Brown was definitely grinding his axe, so he's suspect, and Mansfield was granted permission to publish his take, so that would suggest we're not gonna hear ANY dirt. Certainly not in the Anthology, either.
Which is just as well with me. I'm just interested in the fun stuff, their songwriting ideas and craftsmanship, not the garbage.
