During summer 1970, the skiffle-like song "In the Summertime" by British band Mungo Jerry reached the top of the charts in several countries around the world. In 2017, performer Billy Bragg's book "Roots, Radicals and Rockers", a history of the skiffle movement, was published. Bragg has compared the development of skiffle in Britain in the 1950s to punk rock in the 1970s, noting that skiffle was a revolt by young people against the culture of their parents, and allowed them to create their own style of music without expensive equipment or great musical virtuosity.
