Manfred Mann were a British beat, rhythm and blues, pop, and cover band of the 1960s, named after their South African keyboardist Manfred Mann, who later led the successful 1970s group Manfred Mann's Earth Band. Manfred Mann were chart regulars in the 1960s, and the first south-of-England-based group to top the US Billboard Hot 100 during the so-called British invasion. The Mann-Hugg Blues Brothers (as the band were originally called) were formed in London in December 1962 by keyboard player Manfred Mann and drummer/vibes player Mike Hugg. Born out of the British blues boom then sweeping London's clubs (which also spawned the Rolling Stones, the Moody Blues and the Yardbirds), the band was completed by Mike Vickers on guitar, alto saxophone and flute, Dave Richmond on bass guitar, and Paul Jones fronting as lead vocalist and harmonicist; by this point, they had changed their name into Manfred Mann & The Manfreds. Gigging constantly throughout late 1962 and early 1963, the band soon attracted attention for their distinctive sound propelled by Mann's keyboards, Jones' soulful vocals and the group's overdubbed instrumental soloing.
