I found her vocal track on a cassette tape I recorded in the the early '80's. It was recorded on a 4 track Tascam cassette recorder which I disposed of many years ago. When I played the tape on my stereo cassette player I heard only her voice and nothing else. I then transferred her vocals to my Digital Audio Workstation and made an instrumental backing track using Band-In-A-Box. I also had to make it a duet as the cassette tape was 40 years old and the start of the song was of poor quality. She had a fabulous voice, sang in many different languages and was a very good jazz vocalist. It took a lot of fiddling to sync her vocals to my backing track but at the end it was well worth the time and effort.
