On 24 September 1991, the album "Waking Up the Neighbours" was released. Co-produced by Adams and Robert John "Mutt" Lange, it topped the charts around the world, including in the UK, Canada, Australia and Germany and reached number 6 on the "Billboard" 200. It became Adams's second album to be certified Diamond in sales in Canada while being certified 4x platinum in the US. It went on to sell 16 million copies worldwide. "Waking up the Neighbors" became the first album after Neil Young's 1972 "Harvest" to reach the top of the album charts in the United Kingdom. Ironically, however, the album was launched in Canada amidst a storm of controversy. The album is also known to have caused controversy in Canada due to the Canadian Content system. This indicated that a certain percentage must be broadcast by Canadian music on Canadian radio and television broadcasts. Since "Waking Up the Neighbors" was largely recorded in England and co-produced by Robert John "Mutt" Lange (originally from Zambia), the album and its songs, under the rules in effect until 1991, were not thoughtful purely Canadian productions. Meanwhile, the album was shortly broadcast in Canada, but nevertheless managed to reach the top of the Canadian charts. Following Bryan Adams' complaints, in September of that year, the Canadian Radio-television and Telecommunications Commission (CRTC) announced that the Canadian content rules would be expanded. The old regulation for collaborative writing between Canadians and non-Canadians where the lyricist and musical composer worked separately. In September 1991, the regulation was optimized to recognize unions in which two (or more) contributors each contributed to both lyrics and music, as was the case with Adams and Lange. In protest, Adams briefly threatened to boycott Canada's annual Juno Awards, where his album had been almost completely ignored by the awards committee. He did end up winning the Juno International Achievement Award, Canadian Entertainer of the Year (voted on by the public) and Producer of the Year Award.
