Growing tearful, Whiley called it a “really lovely moment”, adding: “It was really good. She keeps saying, ‘Daddy said my name!’ It couldn't have been better.”Jo Whiley emotionally shared memory of her sister Frances (YouTube)Watch Apple TV+ free for 7 dayNew subscribers only. £9.99/mo. after free trial.

He was the kindest man, who lived solely to make others happy. He was supremely selfless and loved nothing more than caring for others and making people laugh.”The broadcaster said she has received “so many messages” praising her father and describing him as “a character”, which she said “sums him up completely”.Whiley added: “I have Dad to thank for my love of music – he used to walk around the building site where he worked as an electrician with a huge ghetto blaster – the OG DJ and his passion for music never went away.“His love for Elbow, Coldplay and Dido was unrivalled.”According to the NHS, Parkinson's is a progressive neurological condition where parts of the brain become damaged over many years, affecting movement, as well as bodily and mental functions.
