A four-year-old has lent her voice to a protest song released ahead of international demonstrations against dolphin hunting.

Leela Byrne’s Dolphin Song, mixed by DJ Tim Hawkins, will be played outside Japanese embassies at rallies around the globe on August 31 as part of Japan dolphin day 2012.

The four-year-old, from Selhurst, is the daughter of avid campaigner and UK director of volunteer group Earthrace Lucy Byrne.

The 29-year-old said: “When I first became involved I visited Leela’s play school, Stepping Out. To get the kids involved you sing a song and walking home she began singing her own version.

“I filmed it and put it on YouTube, but I then forgot about it. Building to this year’s rally we discussed about having a song, and this came to mind.”

Ms Bryne said documentary the Cove shows Japanese fishermen trapping pods of dolphins before killing them.

She said: “You think these things no longer go on. It is shocking.”

The song was taken and re-mixed by Leela’s uncle DJ Tim Hawkins, who works under the name We Am Legend, and will be used by campaigners around the world.

In total 88 demonstrations are expected, from London and Edinburgh to Australia, Thailand and Brazil.

Ms Byrne said: “This is not about being aggressive or anti-Japan, it is about showing the strength of feeling, and that we will not go away.”

Following the demonstrations the song will be performed in schools around the UK as part of Earthrace’s campaign to stop the hunting of dolphins.
