Watched online, excellent print.
This is not a musical, and doesn't even deserve the Genre Music. Annabella plays the zither and sings once, and she and RY immediately reprise it.
Spoiler alert: I don't need to watch this again, so here's the entire plot, in slightly more detail that the synopsis writer provided. This is just a romcom, with leisure class boy engaged to leisure class girl, reluctant to marry, meets working class girl, falls in love, but attempts reconciliation with the fiancee. Working class girl follows, RY jilts the bride again, marrying the working girl. His father disowns him but immediately hires him to work as shipping clerk in a remote branch of the family firm. And there's an Alpine rescue in there somewhere.
Extra spice & complications added by Walter Connolly as psychiatrist hired by RY's mother to assist the reconciliation.
