We present a recursion relation for a current containing n off-shell plus an arbitrary number of onshell gluons. We are able to obtain an exact solution for n=2 when all of the on-shell gluons have the same helicity, and one of the off-shell gluons is given a "generalized" polarization vector. We then apply this solution to derive an expression for the amplitude for qq̄→qq̄ggg.
