Happy Mondays are an English alternative rock band from Salford, Greater Manchester. Formed in 1980, the band's original line-up was Shaun Ryder on lead vocals, his brother Paul Ryder on bass, lead guitarist Mark Day, keyboardist Paul Davis, and drummer Gary Whelan. Mark "Bez" Berry would later join the band onstage during a live performance after befriending Shaun Ryder and served as a dancer/percussionist/chemist. Rowetta Satchell joined the band to provide backing vocals in the early 1990s.

The band together with some other Manchester bands like The Stone Roses and Inspiral Carpets(where Noel gallagher worked as a roadie)were some of the most influential bands of the Madchester scene in the 80s.
