No. After John had been dead for 16 years the rights to his songs reverted back to the estate. So, she owns them, essentially. She always knew this, so she never wanted to go in with Paul and try to buy them as she knew she'd get them anyway.
I understand there will be another "Lennon Anthology" released this year. Undoubtedly with the exact same old boring seen- them- a- million- times photos and another booklet with pages and pages detailing the many -millions-of-times-John-hurt- me crap. Ah, well, Mother, all the money sure made up for it. Bin-Ono indeed.
