The OPE algebra Q = Q(ga) generated by a pair of oppositely charged 'currents' ~b(z, + g) (Izl = 1) of spin s = 89 (2s --1, 2, 3 .... ) is specified by the leading terms in the small distance expansions of qJ(zl,g)~/(z 2, -g) and ~b(zl,g)~(z2,g). The 'current' ~b(z,g) splits into a product of a U(l)
