Peter, Jan and Cindy have all been accepted into the school's glee club, which results in two divergent stories in the Brady house. On one side, Bobby is depressed since he wasn't chosen along with his siblings. Mike and Carol want to encourage Bobby to explore other possible musical avenues, such as through the school's music program. They may regret doing so after Bobby makes his choice of instrument, and after they have made everyone in the house support Bobby at all cost in this endeavor, no matter how painful (to their ears) it may be. On the other side, Peter is overjoyed to be part of the glee club, that is until his football teammates tease him about it being a sissy activity, especially as he was late to the first football practice with pro-baller
Deacon Jones because of glee club rehearsal. Mike and Carol hope that Peter regains his joy in being part of the glee club and not to worry about what his peers may think or say about it, especially when Peter is thinking about quitting the club solely because of the teasing.
