the fact that artists from Europe and North America were willing to perform in Sun City, a whites-only luxury resort in the "homeland" of Bophutatswana, persuaded artists including Bono, Bruce Springsteen, and Miles Davis, to come together to record the single "Sun City", which was released in 1985. The single achieved its aim of stigmatising the resort. The album was described as the "most political of all of the charity rock albums of the 1980s". "Sun City" was explicitly critical of the foreign policy of U.S. President Ronald Reagan, stating that he had failed to take firm action against apartheid. As a result, only about half of American radio stations played "Sun City." Meanwhile, "Sun City" was a major success in countries where there was little or no radio station resistance to the record or its messages, reaching No. 4 in Australia, No. 10 in Canada and No. 21 in the UK. A number of prominent anti-apartheid songs were released in the years that followed. Stevie Wonder released "It's Wrong", and was also arrested for protesting against apartheid outside the South African embassy in Washington, D.C. A song popular with younger audiences was "I've Never Met a Nice South African" by Spitting Image, which released the song as a b-side to their successful "The Chicken Song". Eddy Grant, a Guyanese-British reggae musician, released "Gimme Hope Jo'anna" (Jo'Anna being Johannesburg). Other performers released music which referenced Steve Biko. Labi Siffre's "(Something Inside) So Strong", a UK top 5 hit single in 1987, was adopted as an anti-apartheid anthem. In 1988, Dammers and Jim Kerr, the vocalist of Simple Minds, organised a concert in honour of Mandela's 70th birthday. The concert was held at Wembley Stadium, and ended with the songs "Biko," "Sun City", and "Bring Him Back Home". Dammers and Simple Minds also performed their own anti-apartheid songs: "Free Nelson Mandela" and "Mandela Day", respectively. Other acts performing at the concert included Stevie Wonder, Whitney Houston, Sting, Salt-N-Pepa, Dire Straits and Eurythmics. The event was broadcast to a TV audience of approximately 600 million people. Political aspects of the concert were heavily censored in the United States by the Fox television network, which rebranded it as "Freedomfest". The use of music to raise awareness about apartheid paid off: a survey after the concert found that among people aged between 16 and 24, three-fourths knew of Nelson Mandela, and supported his release
