Well I don't know. Lennon Murphy got sued by Yoko Ono 15+ years ago for using her own name. But the U.S Trademark Board dismissed the petition. Kurt Loder promoted Murphy for a while on MTV. As far as I know, her career never really took off. A number of years ago, she did play a gig near here which I thought about going to. If you get booked here, it's a given that either you're unknown or your career is already seriously in peril.
