Depends on your age group.
My favourites form the 70�s and 80�s are:
Aussie Rules Football - Up There Cazaly
Cricket - howzat (Sherbet)
Winning - We are the Champions (Queen)
Boxing - The Hurricane (Bob Dylan) & Black Superman Muhammed Ali
Kung Fu - Kung Fu Fighting
However, there is a great kids book of sports songs:
Going, Going, Gone and other Silly Dilly Sports Songs by A Katz. It covers all sports - it�s great.
Good luck!
