Earlier in the evening, The Yardbirds performed at the Ricky-Tick Club in Windsor, which was one of their regular residencies. They then traveled to London to take part in this multi-act benefit for Cyril Davies' family following his death at age 31 on 7 January. Other participating musicians included Georgie Fame, Manfred Mann, Alexis Korner, Jimmy Powell, John Mayall, Zoot Money, The Animals and Cyril's band, The All-Stars, now lead by band member Long John Baldry. (The band would change their name to "Long John Baldry and His Hoochie Coochie Men" in the coming days).
