Murphy, who has been performing under the name Lennon for eight years, was named after Ono’s late husband, and former Beatle singer, John Lennon.
According to TMZ.com, Murphy even successfully registered the stagename as a trademark in 2003 – consulting Ono early on in her career about using it to perform under even though, as it’s her legal name, she didn’t need to.
Ono apparently made no objection at the time but is now stating that Murphy “fraudulently” registered the name as a trademark.
She also added that Murphy’s use of late husband John Lennon’s name is “tarnishment” towards the deceased Beatles member.
Above the posting he states: “She has my full support.”
