Martin Wesley-Smith taught composition at the Sydney Conservatorium of Music from 1974 to 2000. Since then he has lived in Kangaroo Valley, New South Wales. His output, ranging from children’s songs to multimedia pieces, covers two main themes: the life, work and ideas of Lewis Carroll (e.g. Boojum!), and the plight of the people of East Timor (e.g. Welcome to the Hotel Turismo). His twin brother, Peter Wesley-Smith, writes most of his lyrics and libretti; their 70^th birthday, in 2015, was celebrated with concerts in Canberra, Kangaroo Valley and Sydney.
