An Affair of the Heart: Rick Springfield 8 p.m., Epix
Who knew? There is still a rabid fandom around Rick Springfield. Some 40 years after “Jessie’s Girl” and Springfield’s turn on “General Hospital’’ as Dr. Noah Drake, the guy still inspires a devoted following of women and their long-suffering husbands. While touching on Springfield’s depression and suicide attempt, as well as the strains on his marriage, this documentary focuses on the reciprocity between Springfield and his worshipers. I guess, like Deadheads or Parrotheads, they should be called, uh, Rick-heads.
Nashville 10 p.m., ABC
With Chris Carmack’s Will (right), the “Nashville” writers have come up with an interesting character. He’s a cowboy musician in Nashville who drunkenly makes a move on his new buddy, Gunnar, who lives with his girlfriend, Scarlett. Is Will gay? Bisexual? Will other characters reject him? Gunnar (Sam Palladio, left) is already angry at him, but it’s hard to tell if that’s a reaction to Will’s sexuality or to being hit on while already in a relationship.
