I think Frank is referring to his first wife of long ago. The one he left for the Connecticut musician trophy wife.
Yeah, it's Sparkly, airhead Monica Dale, and she's a moonbat:
While studying dance in New York City and earning a B.A. in Music from Connecticut College, Dale recognized a “kinesthetic music†in movement. She then pursued Jaques-Dalcroze Education with Jack Stevenson at Ithaca College, receiving her Jaques-Dalcroze License and MM in Piano Performance. She continued a dual career in music and dance, as well as Dalcroze Eurhythmics
I like the Eurythmics. "You can fool with your brother, but don't mess with the Missionary Man."
