Joseph Allan McIver (17 January 1904 – 15 June 1969) was a Canadian composer, arranger, pianist, and conductor. As a pianist he performed with orchestras in the Quebec region in his early career and was the longtime accompanist and arranger for Trio lyrique. He had a long and fruitful relationship with the Canadian Broadcasting Corporation, serving as a music director, composer, arranger, conductor, and pianist for nearly four decades.
Born in Thetford Mines, McIver grew up in Sherbrooke. In his youth he studied the violin and the flute and was a piano student of Alfred Whitehead. He later studied harmony with Oscar O'Brien. He started his performance career playing for silent films in Montreal in 1926. He began performing on Canadian radio programs as a pianist and singer (baritone) around 1930. In the early 1930s he started appearing as a concert pianist with orchestras like the Ottawa Philharmonic Orchestra.
In 1932 McIver was enlisted to work as an accompanist and arranger for Trio lyrique (TL), a newly formed vocal trio in Montreal that consisted of baritone Lionel Daunais, contralto Anna Malenfant, and tenor Ludovic Huot. Jules Jacob replaced Huot in the early 1940s. In 1933 the ensemble was engaged by CRBC for its network series One Hour with You, on which the group performed for 87 weeks. In 1934 the TL released the LP album Chansons de Lionel Daunais for Radio Canada International. In 1936 the group performed for the CBS radio network in New York where McIver was also engaged as a staff arranger.
