Scottish comedian Billy Connolly, known as "The Big Yin", was diagnosed with Parkinson's in 2013 and retired from stand-up five years later.
Despite experiencing growing physical challenges, Connolly has maintained a positive outlook, previously stating he doesn't feel "close to death".
Connolly revealed he was diagnosed with both Parkinson's and prostate cancer on the same day, but has since received the all-clear from prostate cancer.
Kay praised Connolly's significant influence on other comedians and is embarking on a new tour with all proceeds going to various cancer charities.
