Deus Solus (meaning God Alone) was composed for the Melbourne Staff Band's 130th anniversary at the request of Bandmaster Ken Waterworth. It is based on three Christian tunes - the 18th century hymn O God, our help in ages past (S.A.S.B. 47), and the more contemporary songs God and God alone (Phill McHugh) and Chris Bowater's Faithful God (S.A.S.B. 360). The work begins quietly and with a sense of the unknown, with references to O God, our help in ages past, alluding to the formation and early days of the band.
