text: In a 1990 press conference, Paul McCartney recalled meeting Sullivan again in the early 1970s. Sullivan apparently had no idea who McCartney was. McCartney tried to remind Sullivan that he was one of the Beatles, but Sullivan obviously could not remember, and nodding and smiling, simply shook McCartney's hand and left. In an interview with Howard Stern around 2012, Joan Rivers said that Sullivan had been suffering from dementia toward the end of his life.
  Politics
  Sullivan, like many American entertainers, was pulled into the Cold War anticommunism of the late 1940s and 1950s. Tap dancer Paul Draper's scheduled January 1950 appearance on Toast of the Town met with opposition from Hester McCullough, an activist in the hunt for "subversives". Branding Draper a Communist Party "sympathizer", she demanded that Sullivan's lead sponsor, the Ford Motor Company, cancel Draper's appearance. Draper denied the charge, and appeared on the show as scheduled. Ford received over a thousand angry letters and telegrams, and Sullivan was obliged to promise Ford's advertising agency, Kenyon & Eckhardt, that he would avoid controversial guests going forward. Draper was forced to move to Europe to earn a living.
  After the Draper incident, Sullivan began to work closely with Theodore Kirkpatrick of the anti-Communist Counterattack newsletter. He would consult Kirkpatrick if any questions came up regarding a potential guest's political leanings. Sullivan wrote in his June 21, 1950, Daily News column that "Kirkpatrick has sat in my living room on several occasions and listened attentively to performers eager to secure a certification of loyalty."
