Problem: Tristan da Cunha:

The Tristan Song Project was a collaboration between St Mary's School and amateur composers in England, led by music teacher Tony Triggs. It began in 2010 and involved St Mary's pupils writing poems and Tony Triggs providing musical settings by himself and his pupils. A desktop publication entitled Rockhopper Penguins and Other Songs (2010) embraced most of the songs completed that year and funded a consignment of guitars to the School. In February 2013 the Tristan Post Office issued a set of four Song Project stamps featuring island musical instruments and lyrics from Song Project songs about Tristan's volcano and wildlife. In 2014 the Project broadened its scope and continues as the International Song Project.
