One of Beverley Sisters' twins, Babs Beverley, died at the age of 91.
Her death, together with her sister Joy in 2015, leaves Teddie Beverley as the only surviving member of the vocal harmony group.
Born in Babette Chinery in 1927, Babs grew up with his brothers at Bethnal Green in eastern London.
The trio was one of the most popular moves of the 1950s and '60s and enjoyed the success of the charts with records like I Saw Mommy Santa Causings.
Their other hits include Little Drummer Boy, Bye Bye Love and Irving Berlin standard sisters.
They had their own BBC TV show in the 1950s, and they were produced in 2006 as an MBE.
The group actually retired after Joey married Billy Wright, an English football team captain in 1958.
However, they met again in the 1980s, and in 2002, they entered the Guinness Book of World Records as the longest surviving vocal group without changing the lineup.
