Shakin' Stevens, also known as "Shaky" (born Michael Barratt, 4 March 1948) is a platinum-selling Welsh rock and roll singer and songwriter who holds the distinction of being the UK's biggest-selling singles artist of the 1980s. His recording and performing career began in the late 1960s, although it was not until 1980 that he saw commercial success in his native land. In the UK alone, Stevens has charted 33 Top 40 hit singles.

Michael Barratt, who would adopt the stage name Shakin' Stevens, was the youngest of 11 children born in Ely, a suburb on the outskirts of Cardiff in South Wales to Jack and May Barratt. His father was a First World War veteran who by 1948 was working in the building trade. The oldest of his siblings were born in the later part of the 1920s, and by the time of his birth some of them were already married and had children of their own. Jack Barratt died in 1972 at the age of 75, while May survived until 1984 and the age of 79.

Shaky married his wife Carole on 7 October 1967 and they have three children. At the time of their marriage, his official occupation was a milkman, and they lived in a flat which formed part of an office block in inner-city Cardiff. The office block was demolished several years later.
