My Old Man song is a football song sung by fans of English and Northern Irish Association football clubs. Usage has declined in recent years as the aspects of hooliganism it depicts has also decreased. It is sung to the melody of the song "Don't Dilly Dally (My Old Man Said Follow The Van)", popularised by Marie Lloyd. Different versions of the song are sung by different sets of fans. It was initially sung by Aston Villa fans about their cross-city rivals Birmingham City.
