Roy Cazaly (13 January 1893 – 10 October 1963) was an Australian rules football player famous for his high marks and ruck work, which gave rise to the phrase "Up There Cazaly".
The idea for the song began in November 1996 when two Derby County supporters Mark Tewson and Martyn Miller heard an old Australian rules football song entitled "Up There Cazaly" which was composed by Mike Brady, in 1979, for an Australian TV show.
