The Yardbirds put their unique spin on American Blues recordings and came up with a lot of their own material based on this new sound, which involved changing rhythms and buildups, which came to be known as the "Rave Up." This is one of the band's original compositions, and the words were written by their bass player, Paul Samwell-Smith. When we spoke with Jim McCarty, who was The Yardbirds drummer, he explained: "Paul really came up with those lyrics. It was very reflective, quite sensitive about losing it, losing a girlfriend or whatever, and about things he saw in nature. The lyrics were something we were quite interested in doing. But they ranged from all sorts of things. Keith (Relf) and Paul were particularly good at those."
