On how well those songs are ACTUALLY SUNG:

I knew the "Sons Of The Pioneers", and the "Riders In The Sky" are NO "Sons Of The Pioneers" (as a guy said in a presidential debate once)! Humor and phony campfires and and tumbleweeds blowing from stage-left and rubber chickens "frying" in the frypan might be funny, but NOBODY sang those songs as well as Bob Nolan and The Sons! It bothers me to hear the "Riders" mess up that genre.

Just my humble opinion.
