White Riot Tour
This was the first full scale tour by the band, not considering the Dec 1976 "Anarchy Tour" supporting the Sex Pistols, all but three shows of which were cancelled.
Their first album in the UK had been released just weeks prior, and new drummer Topper Headon was now in the mix providing both needed chops and power to the live show.
Sourced from low gen audience sources, and has reasonably clear sound quality for an audience recording of the time.
