The title song of the 1959 Jack (Billy The Kid) Buetel western MUSANG! sung by the amazing Champ Butler (so amazing I couldn't find any info on him) sounds like it could have been lifted from the credits of many a spaghetti. This modern western was co-written and directed by the late great Tom Gries (100 RIFLES & THE RAT PATROL.) Another favorite who departed this earth way too soon....at the age of 55.
The 1972 Robert Mitchum south of the border "American" oater THE WRATH OF GOD (not to be confused with the 1968 spaghetti WRATH OF GOD with Montgomery (Brett Halsey) Ford seems and feels more spaghetti to me than Mitchum's 1978 VILLA RIDES which was actually filmed in Almeria. Some of the movie is set in a town that is a mirror image of Los Albaricoques and co-star Ken Hutchison evoked memories of Lou Castel in A BULLET FOR A GENERAL.
