OK, pretty unusual statistic, but I wonder who has lived the longest since their last recording?
This springs to mind for me with a few performers who were on 78rpm. Bob and Alf Pearson last recorded in 1953, and Alf lived to be 102 when he died in 2012 - so it had been 59 years since he last had a recording out (I think his spoken word contributions to a compilation can be ignored!). Betty Driver's last recording was in 1954, and she lived another 57 years.
However, 50s entertainer Diana Decker was recording regularly from 1950 to 1956, when I believe her output stopped. She's 92 now and it's 60 years since she had a recording out!
I suppose anyone still alive who briefly recorded in the early '50s or earlier would clinch this, but I find it remarkable that those artists have no recordings beyond that period.
Now Kirk Douglas is turning 100 soon and he may not have released any music since 1955, which is 61 years, but I think people who had continuous recording careers are more notable by their absence from the studios!
