The group consisted of Alistaire "Alex" McCalla, Roshaun "Bay-C" Clarke, Craig "Craigy T" Thompson, and Xavier "Flexx" Davidson. The group's origins can be traced back to the early 1990s while the members were still attending school. Alistaire McCalla and Xavier Davidson were friends, and McCalla recruited Craig Thompson and Roshaun Clarke who were fellow members of the choir at Campion College in Kingston and T.O.K. was born.
