Hepworth is particularly good at stripping away the glamour of the invasion bands’ first trips to America, which came at a time when few Brits travelled further than Clacton-on-Sea. Acknowledging the Rolling Stones as bona fide music snobs obsessed with American blues and jazz — Brian Jones tried to pass himself off as bluesman Elmo Lewis, despite coming from Cheltenham, “where Elmos are rare” — Hepworth goes on to describe the realities of the Stones’ US experience, such as finding themselves sharing the bill with a troupe of chimpanzees in San Antonio in 1965. For the Animals it was worse. After the success of House of the Rising Sun, Eric Burdon’s band assumed they would be greeted as serious musicians. Instead they found themselves on a TV special with Liza Minnelli, where they were called on to wear wolf’s ears and tails and mime to a song called We’re Gonna Howl Tonight.
