This poster is for when the Clash did a residency at Bond's International Casino (now Bond 45, a restaurant) in Times Square in 1981. They played 17 shows in three weeks to support "Sandinista", which, by the way, is one of my favorite albums of all eternity; so as you can guess, I would just about die to be around at that time!!!! And to top it off, the opening bands included the Fall, the Slits, the Dead Kennedys, Bad Brains, and Bush Tetras – all the goods.
It's worth mentioning that all the shows were sold out and they caused fire hazards, riots, police intervention, etc.
For VERY extensive details about the residency, check out this site. It has scans of all associated news articles, set lists, photos, and a timeline of events.
