Check out PAT and VICTORIA GARVEY.
Pat was a unique writer in Chicago for several years in the early 1970s. He and his wife Victoria were a nationally accepted performing team then. She played piano and was more pop / cabaret than was her husband who played acoustic guitar. Had a good blend together. She went off with other guys and continued to play some of the so-called better venues. (That meant more nightclubby bars in more urbane settings---the same places she'd played when she and Pat were a duo. Places like The Quiet Knight in Chicago---upstairs at Belmont and Sheffield. The Cellar Door in Washington D.C. etc. The Quiet Knight lasted until the first Mayor Daley busted the place on a technicality of the liquor laws. (Being on the second floor, one could not "see in from the street". You had to be able to see in from street level of bars then. It was a little-used rule reserved to stomp on one's foes when the need arose in Chicago at that time and the "shoe fit" the situation.)
The CRIME Richard Harding had committed was that he had allowed a benefit to take place at his club for Dick Simpson--an independant alderman at the time and a foe of Richard J. Daley's.
Pat Garvey didn't really get going as a solo performer after the breakup of the duo as I recall those times.
