The show begins with composer Geoffrey Hudson teaching the audience to sing a simple tune. Then follows the broadcast of A Passion for a Planet with director’s-cut-style annotations by Hudson and climate scientist Michael E. Mann, which include graphs, backstory, and musical examples. The eco-oratorio ends with audience members and performers joining to sing the tune learned at the top of the program, providing a sense of unity and underscoring the message that we all have parts to play in this campaign to save our planet. As vital participants in the work to be done, viewers can engage in real-time with the panelists via chat and join the performers to sing the final chorale.
