The two-dimensional non-abelian Bose-Fermi equivalence in the presence of background gauge fields and "Kaluza-Klein" scalar fields is derived. It is shown that a current-current interaction linear in the background scalar field in the Fermi version leads to interactions which involve all orders in the background scalar fields in the Bose version of the theory. Implications for the possible embedding of the heterotic string in the closed bosonic string with a special choice of background fields are discussed.
