Monterey also marked a significant changing of the guard in British music. The Who and Eric Burdon and the Animals represented the UK, with the Beatles and the Rolling Stones conspicuously absent. The Stones' Brian Jones was seen many times strolling through the crowds, resplendent in full psychedelic or psychedelia regalia, and appeared on stage briefly to introduce Jimi Hendrix. It would be two more years before the Stones went on tour, by which time Jones was dead. The Beatles had already stopped touring altogether. Meanwhile, the Who leapt into the breach and became the top British touring act of the period.
