"At the End of the World, I Am!” is a Community Music Therapy musical, written by choir members, marginalized groups of people in Israel. The musical was written as a result of Participatory Action Research (PAR) which took place a few years earlier in collaboration between a music therapist, a researcher and members of two choirs, Renanim (people with severe physical disabilities) and Idud (people with Intellectual and developmental disabilities). At the time, PAR approach was born out of disagreements about yearly mutual performances between the choirs and a desire to change and improve a quest namely, ' to give voice' to Renanim choir. Renanim choir had fewer members than Idud and their voices had some limitations. Renanim choir had an agenda of social change and were not only concerned about being heard during performances.
