In 1981, after their scorching single Ghost Town went to No 1, Hall, Golding and Staple left to form the Fun Boy Three. The remaining Specials added more members and continued as the Special AKA, before splitting in 1984 (though Dammers was held in a record company contract until 1987). Since then, there have been various Specials reincarnations. People have been in and out (30 members since 1979: Wikipedia has resorted to a graph).
Panter was an art teacher for special needs children for a while, Golding moved to Seattle. He and Hall didn’t speak for more than a decade. Neither Dammers nor Hall rejoined for years. Hall was focused on his solo career. Dammers – who started the group and owned their name – tried to restart the Specials in the late 00s on the condition that they play new material. They got as far as two rehearsals before everyone fell out again.
