British rock 'n' roll was a style of music that became popular in the late 1950s.
Young people liked it because it was loud and fast.
Musicians were influenced by American films such as Rock Around the Clock (1955) starring Bill Haley & his Comets.
Several stars were discovered or performed live at the 2i's Coffee Bar in London, such as: Tommy Steele, Cliff Richard and Wee Willie Harris.
As record players were made cheaper in the 1950s, more people could afford to buy them and so enjoy listening to rock 'n' roll music at home.
