My First cousin, Charlotte Rogers McElroy, was a trained operatic singer. She sang for Pres Nixon in the White House.
Many years later, after she was diagnosed with serious heart and lung disease, she came home. About a year or so before she died, she made a recording of an assortment of songs. She paid a studio in Nashville, my sister went with her to drive, and she also sang harmony on three of the songs.
On this one, I recorded the piano as a midi, which she carried with her to the studio and recorded herself singing along with my piano playing.
