Madness are a pop/ska band from Camden Town, London, England that formed in 1976. As of 2007, the band has continued to perform with their most recognised lineup of seven members, although it's varied slightly over the years. They were one of the most prominent bands of the late-70s 2 tone ska revival. However, as their career progressed, the band moved away from ska & closer toward conventional pop music.
Madness achieved most of their success in the 80s. Madness spent exactly 214 weeks on the UK singles charts from 1980-89, thereby sharing the record for most weeks spent by a group in the 80s UK singles charts, with UB40.
