The Pink Floyd rock classic Another Brick in the Wall has been transformed by a Canadian band into an anthem of dissent for young Iranians.
The song replaces the teacher reference with "Hey, Ayatollah, leave those kids alone!"
It is performed by a Toronto-based rock band fronted by two Iranian brothers called Blurred Vision and has been seen by more than 160,000 viewers on YouTube.
Pink Floyd founder Roger Waters gave Blurred Vision permission to use the song. Proceeds will go to Amnesty International.
The Blurred Vision version of the song expresses the tension between young people and the government of Iran, where it is illegal to play rock music.
Waters will begin his tour of The Wall in Toronto on September 15. Another Brick in the Wall is from that classic 1979 album.
