Mackintosh was one of Britain's most distinguished bandleaders of the 20th century, accompanying singers such as Tom Jones, Shirley Bassey and Matt Monro. He was born in Halifax Road, near Knowler Hill, in 1919 and devoted his life to music, after buying his first alto saxophone, at the age of 15. After a period in the Army he went to London and joined various big bands such as the Oscar Rabin Band. He then formed his own orchestra and toured extensively at home and abroad. The orchestra was featured on BBC Radio, almost every week, in the 1950s and early 1960s.
