Cockles and Mussels is a popular old Irish song. It's the story of Molly Malone.
Molly Malone was a sweet girl who lived in the city of Dublin. She was a fishmonger who used to wheel her wheel-barrow full of cockles and mussels through broad and narrow streets.
Her father and mother were fishmongers too, and she learned from them what to cry while wheeling her barrow in order to sell her cockles and mussels.
It is a sad song, because it tells us that she died of fever, and there was no one who could save her.
But her ghost wheels her barrow on the streets of Dublin, crying "cockles and mussels alive, alive, oh!"
