the annual Sunbury music festival, held outside Melbourne, Victoria each January from 1972 to 1975. Although there were numerous other smaller festivals, most were not successful and failed to have the lasting impact of Sunbury. After the disastrous 1975 Sunbury festival, which sent the promoters broke, large-scale festivals were considered too risky and were only occasionally staged in Australia until the advent of the annual Big Day Out in the 1990s. Also paralleling a US trend was the beginning of an Australian Christian music culture. One of the first examples of this trend was the surprise success of singing nun Sister Janet Mead whose 'rock' arrangement of The Lord's Prayer was a major hit in Australia and the US and earned a gold record award in the US. Bands like Family in Brisbane, and Kindekrist in Adelaide, started performing. Rod Boucher formed Good God Studios, which recorded a range of alternative Christian artists. Following on these foundations, later artists such as Newsboys had significant popular success. Two important changes which had a dramatic effect on the rock scene were the long-overdue introduction of colour television and FM radio in 1975. This period also saw the decline of the booming local dance and discothèque circuit that had flourished in the 1960s and early 1970s. These rock dances were a continuation of the social dance circuit that had thrived in Australia's cities and suburbs since the 19th century, and they were hugely popular from the late Fifties to the early Seventies, but they gradually faded in the early Seventies as the "Baby Boomer" generation grew into adulthood and changes to licensing laws saw pubs take on an increasingly important role as venues for live music. From the 1950s to the early 1970s, the main venues for live music were discothèques (usually located in inner city areas), church, municipal and community halls, Police Boys' Clubs and beachside surf clubs. Bigger concerts and international tours were usually staged in the few large-size venues, such as the Sydney Stadium (originally built as a boxing arena), the Sydney Trocadero, and Brisbane and Melbourne Festival Halls. Such venues regularly attracted large numbers of young people because they were supervised, all-ages events—Australia's restrictive liquor licensing laws of the period meant that these venues and dances were almost always alcohol-free. According to rock historian Glenn A. Baker, in 1965 there were up to 100 dances being held every weekend
