81 is a pretty good run. I watched a documentary on her last year. She was a work horse of a performer, and a total pro. No entourage. She'd fly commercial into some small regional airport and be picked up by someone from the gig, usually a casino. Get her self ready, do the gig and hit the sack. Up the next day and rinse and repeat to a new gig. Her humor wasn't my thing in her last 15 years or so, but I did admire her attitude towards performing and being a pro.
