The streets of Glenoak are alive with the sound of music as the Camden family breaks into song for a very special Valentine's Day musical episode. Classic songs (""Love Is Sweeping the Country,"" ""You Were Meant For Me,"" ""Nice Work If You Can Get It,"" among others) are performed by the Camdens.

Simon is enjoying having his new girlfriend, Anna, who he just met the day before over at his apartment for Valentine's Day. They both agree to go to Glen Oak, but he decides to keep her away from his family for the time being. Annie displays her unhappiness to Simon in song (along with the rest of passerbys) over his constant dating habits at the promenade as the chorus is going on. Anna overhears this and begins to question Simon and his dating habits as well. Vincent confronts an unhappy Ruthie on the high school bleachers as she's not in the Valentine's Day mood and is upset over watching Martin practice with his team and Zoe blowing kisses at him.

Also, Lucy and Kevin dance to ""You Were Meant
