The 40 members of an act with a combined age of more than 3,000 are having an Internet hit with their version of The Who’s "My Generation."
The Zimmers, brought together by the documentary-maker Tim Samuels as part of the BBC’s "Power To The People Series," had 1.5 million YouTube views in two weeks.
The interview requests are pouring in from such far-reaching places as Brazil, Germany, Japan and Iceland.
Already confirmed is an appearance on U.S. TV as guests on Jay Leno’s "Tonight Show."
"I haven’t been on a plane since 1927 so it will certainly be an adventure," 99-year-old vocalist and multi-instrumentalist Winifred Warburton told the U.K.’s Daily Telegraph.
The act and the BBC program have a more serious side, highlighting the problems faced by the 3.5 million elderly people who live alone in the U.K.
"If you can judge a society by the way it treats its older people, I always suspected that we’d be in trouble in this country," Samuels told the Telegraph.
