Yeah, there isn't much compared to other soaps of the time, but, in the later years, there was usually music playing in the scenes set at Ryan's, which I suppose could be enough to make further airings cost prohibitive (One use of music I particularly remember involved Ryan Fenelli listening to Madonna's "Like a Virgin" as she considered losing her virginity to D.J. LaSalle).
Yep, the Greer saga was the focus of Labine & Mayer's brief stint in 1983, which won the show's sixth and final Emmy for Outstanding Writing. There are tons of clips of it on YouTube (for reference, the story ran from April 1983 to August 1983).
