My two favorite musical westerns are Oklahoma and The Unsinkable Molly Brown.
You've got two great booming male voices in Gordon McRae and Harve Presnell and two of the best women in musicals in Shirley Jones and Debbie Reynolds. You just can't go wrong with any of that.
Also, what about Seven Brides For Seven Brothers? Howard Keel was up there with both McRae and Presnell with a fantastic voice and Jane Powell was a great musical actress.
I haven't seen Seven Brides for Seven Brothers in years, like maybe 40 years or more. I loved it as a kid. Gotta go find it and watch it.
