This music video is Greenpeace, by Dutch band Teach-In.
This year the Eurovision Song Contest was a pretext for a British Conservative politician for anti-Irish racism.
In 1975, Teach-In won the Eurovision Song Contest. Since then, there have not been any Dutch winners of the contest.
In 1979, they made this song about Greenpeace. The song mentions the Greenpeace ship Rainbow Warrior; in 1985 blown up in a murderous attack by the French secret police because of opposition to French nuclear bomb testing in the Pacific.
