As yet another person named after John Lennon, I have to say that I side for the most part with Ms. Murphy. If Yoko were filing suit because she thought the band were going to actually confuse music listeners into buying the wrong product, she might have a point; as it is, she's accusing the young woman of "tarnishing" John's name, which is prudish, closed-minded, and certainly tenuous grounds for a trademark-infringement claim.
