Looks like I won't have any luck. I checked four Claudia Schmidt CD's, "Essential Tension," "It Looks Fine From Here," "Big Earful," and "Closing the Distance." Didn't have luck with any of them. When she was a regular on Prairie Home Companion, she often did songs not in her usual repertoire, so it's quite possible this one didn't end up on a CD.
