In the classical analysis we show how this model includes various known two-dimensional field theories. Then we perform the calculation of the path integral in a general gauge, and demonstrate that the derived partition function reduces to the familiar form in the case of 2d Yang-Mills theory.(AmsTex) 10 pages, Talk given by T.S. at the international workshop "Physical Variables in Gauge Theories", Dubna (Russia), 21-25 September 1999 (to appear in the proceedings)High Energy Physics - Theorytext
