AGMP Presents LONDON CALLING PLAY THE CLASH 'Should I Stay or Should I Go' Tour. London Calling play The Clash are widely referred to as "the only tribute band that matters". Now that The Clash are no more London Calling are the finest celebration of one of the best groups of all time. The 'Should I Stay or Should I Go' tour sees London Calling perform the hits and fan favourites from the extensive back catalogue of The Clash. The Clash formed in 1976 and are considered one of the most influential groups to come out of the original wave of the Punk scene. Musically, The Clash went on to fuse reggae, dub, funk, rockabilly, disco and hip hop before they disbanded in 1986. An AGMP Concerts presentation.
