MACK’REL UP THE WALL
Now it’s fishing fever times
People run with rod and line
It’s out of May and into June
There’s mack’rel up the wall

A curious song about the annual mackerel run that used to occur in Plymouth, UK. It is part of local oral history that each summer large mackerel shoals arrived in the nearby coves. Someone would shout, “Mackerel up the wall”. Once the alarm was raised, all the townspeople would rush out of their houses and down to the water’s edge where whole families would fish for their supper. The supply was so plentiful, you were able to fish with just ‘sticks, string and old bent pins’

I tried to find a recording of the song on-line but had no luck. ??
