Guinness World Records, known from its inception in 1955 until 1999 as The Guinness Book of Records and in previous United States editions as The Guinness Book of World Records, is a British reference book published annually, listing world records both of human achievements and the extremes of the natural world. Sir Hugh Beaver created the concept, and twin brothers Norris and Ross McWhirter co-founded the book in London in August 1955.
A UK choir called the Prime Timers, with members aged 87 to 99, set a new Guinness World Record for the "world's oldest choir".
The singers, aged between 87 and 99, break the Guinness World Record for the oldest choir.
