Oasis are probably the most successful British pop group since the Beatles. Formed in Manchester in the early 1990's with an original line-up of Liam Gallagher, Noel Gallagher, Paul McGuigan, Paul Arthurs and Tony McCarroll. The brothers Liam and Noel Gallagher are front-men for the band, writing most of the material and behaving outrageously at any public appearance they make.
