Mike Brady AM (born Michael Brady; 28 February 1948) is an Australian musician most commonly associated with the Australian rules football anthems "Up There Cazaly", referring to 1910s St Kilda and 1920s South Melbourne player Roy Cazaly, and "One Day in September".
"Up There Cazaly" topped the Australian singles charts in September 1979 and briefly held the record as best-selling Australian single.
Both songs have become synonymous with Australian rules football and are traditionally sung on AFL Grand Final day in September.
