Renato e Seus Blue Caps (also known as Bacaninhas do Rock da Piedade) is a Brazilian rock band formed in the city of Rio de Janeiro in the late 1950s. They are considered one of the most important groups of the Jovem Guarda movement, and they have written many Portuguese language versions of The Beatles' songs. The first name was censored radio and Jair de Taumaturgo suggested the final name, inspired in Gene Vincent and His Blue Caps.
