and this was in a post......in a letter answering the question again...it got us a free autograph tho and he spelled morphed wrong....
Ever the showman, Rory who had already changed his name, suggested that I adopt a flashier stage name. Because of my penchant for wearing rings on my fingers, I naturally evolved into "Rings" and then quickly morfed into the more Western sounding "Ringo." My last name,Starkey, became shortened to Starr because it fit better with Ringo and so that my solo offering could be billed as "Starr Time." My big numbers included "Boys", "You're Sixteen," "Big Noise From Winetka," and "Alley Oop."
