Slade is a British glam rock band. The band formed in the late 1960s as R&B act, The N'Betweens, and later as the folk-rock act Ambrose Slade, but found great success in the early 1970s, releasing a series of popular singles in what was perceived as being a glam rock style. Slade remain one of the most recognisable acts of the glam rock movement, and were, at their peak, the most commercially popular band in the UK. The band is possibly most famous for the song "Merry Christmas Everybody", originally released in December 1973 , which was never deleted and is heard regularly at Christmas time everafter; it is now the most iconic British Christmas pop song.
