Irene Ryan
She was born on October 17,1902, approximate date given for this picture was 1920. On March 10, 1973 she had a stroke and passed on April 26, 1973 at the age of 70.
The Beverly Hillbillies ran from 1962-1971. Medicare was started in 1965. She would have become eligible for Medicare in 967. The Roy Rogers & Dale Evans Show ran for 3 months, September 29, 1962 until December 22, 1962.
Thus, depending on the date that she appeared on the show, she would have been 59 or 60.
So, she really wasn't yet eligible for Medicare when we see her singing that song. Who would have guessed. 🤣
