"Hi, canny man hoy a ha'penny oot" is a famous Geordie folk song written in the 19th century by Harry Nelson, in a style deriving from music hall.
The song is based on the old Geordie tradition, which was still a common occurrence in the 1950s, and still (very occasionally) takes place today.
As the bride and groom were leaving the church, they would throw coppers to the boys and girls gathered around outside.
These words were eventually written into the song – as "Hi, canny man hoy a ha'penny oot, Ye'll see some fun thor is ne doot, Where ivvor Aa gan ye'll heor them shoot, Hi, canny man, hoy a ha'penny oot."
Chorus: Hi, canny man, hoy a ha'penny oot, Ye'll see some fun thor is ne doot, Where ivvor Aa gan ye'll heor them shoot, Hi, canny man, hoy a ha'penny oot.
