"Higher Love" by Steve Winwood was the main song from the soundtrack for "Big Business" (1988, starring Lily Tomlin & Bette Midler). When Sol tells Frankie Steve Winwood wrote "Higher Love", to which Frankie replies, "Who the hell is that?"
One of the themes for Season 3 of the show is Grace and Frankie going into business together, creating a line of vibrators for older women with arthritis. The seed for this idea is planted in this episode, after Grace is gifted a vibrator from her late friend Babe and suffers from a sore hand as a consequence.
