Jab has 2 Sham 69 concerts.

They formed in Hersham, UK in 1976. Sham 69 lacked the art school background of many rock bands of the time, and brought in football chants, drinking songs and a sort of inarticulate political populism. The band had a large skinhead and hooligan following, which helped set the tone for the Oi! movement. Their concerts were notoriously plagued by violence, and the band ceased live performances after one of their gigs at Middlesex Polytechnic in 1978 was broken up by National Front skinheads fighting and rushing the stage.
