Terry Jones

FILE – This April 24, 2015 file photo shows Terry Jones at a special Tribeca Film Festival screening of “Monty Python and the Holy Grail” in New York. Celebrations for the 40th anniversary of the Monty Python comedy classic “Life of Brian” are being somewhat overshadowed by the health news of Jones. Jones is “very robust” although “on the downhill slope” due to dementia, according to his friend and colleague Michael Palin. Jones was diagnosed in 2015 with a form of dementia that impairs the ability to speak.(Photo by Andy Kropa/Invision/AP, File)
