I had the opportunity to look over her shoulder, so to speak, when she was editing a video at Compact Video in Burbank in the late '70s. She was in charge, relaxed, open to hirelings input, and, in a word, professional. While I was not exactly a fan of her music, I can say that I heard "Last Dance" about a trillion times at bars announcing "Last Call".
Rest in Peace, Donna.
