Swan Song first aired on March 3, 1974, as a 90-minute episode of Columbo. Johnny Cash stretches his acting range to play a country-western star. When Cash's evangelist wife Ida Lupino uses his talents to raise money for her somewhat questionable cause, Johnny would like a slice of the pie. She refuses; he responds by killing her. Lieutenant Columbo (Peter Falk), as is his wont, pokes and prods around in hopes of getting Cash to confess. ~ Hal Erickson, Rovi
