LOS ANGELES 鈥 American singer Tony Bennett is stepping back from concert performances at the age of 95, his son said on Friday.

Mr. Bennett, who was diagnosed with Alzheimer鈥檚 disease in 2016, canceled a run of concerts planned for later this year and won鈥檛 be returning to touring, his manager son Danny Bennett told Variety in an interview.

鈥淭here won鈥檛 be any additional concerts,鈥 Danny Bennett said. 鈥淭his was a hard decision for us to make, as he is a capable performer. This is, however, doctors鈥 orders… We鈥檙e not worried about him being able to sing. We are worried, from a physical stand point, about human nature. Tony鈥檚 95,鈥 he said.

Mr. Bennett, best known for his signature ballad 鈥淚 Left My Heart in San Francisco,鈥 made his two last live performances earlier this month at Radio City Music Hall in New York with Lady Gaga in a show called One Last Time.

The duo recorded a second album of classic duets between 2018 and 2020 that will be released in October. A video showing them recording the single 鈥淚 Get a Kick Out of You鈥 was released last week and showed the 18-time Grammy Award winner in good form.

鈥淗e has short-term memory loss. That, however, does not mean that he doesn鈥檛 still have all this stored up inside of him. He doesn鈥檛 use a Teleprompter. He never misses a line. He hits that stage, and goes,鈥 his son said of the Radio City concerts. 鈥淭ony may not remember every part of doing that show. But, when he stepped to the side of the stage, the first thing he told me was: 鈥業 love being a singer.鈥欌

Mr. Bennett started his career in the 1950s after being discovered by comedian Bob Hope. 鈥 Reuters
