I've met the dad two times, once on a bus and once at my place of work. He is "on" all the time, as Ringo Starr, and is full of helpful bicycling tips.
I like to think she undesrtands things clearly, but knows that being Ringo Starr is all her father has left, and decided to go on a stupid TV Show and do a stupid little dance just as an excuse to tell the World his story so he could watch her from home and cry tears of joy and be happy.
