Heard her last night in Kingston celebrating her 93rd birthday. Harvie S on bass and Alan Broadbent on piano. Sheila moved without help from a device, e.g., cane, or a person. Concert was about 80 minutes. She left the stage for 10 minutes to sit on a couch while Alan and Harvie did their thing. Sheila stood while she sang and when she did not, she saw on a chair. Pretty impressive. Still had some vocal range and man she could still phrase and scat.
