Madness are a British pop/ska band from Camden Town, London, that formed in 1976. In 2009, the band have continued to perform with their most recognised lineup of seven members, although their lineup has varied slightly over the years. They were one of the most prominent bands of the late-1970s 2 Tone ska revival.
Madness achieved most of their success in the early to mid 1980s. Both Madness and UB40 spent 214 weeks on the UK singles charts over the course of the decade, holding the record for most weeks spent by a group in the 1980s UK singles charts. However, Madness achieved this in a shorter time period (1980–1986).Content: http://en.wikipedia.org/wiki/Madness_(band)
