was added, running from Thursday 6 to Sunday 9 August. 1960s The National Jazz Federation (NJF) Festival was established at the height of the trad jazz boom, as a successor to the Beaulieu Jazz Festival, initially as a two-day event held at Richmond Athletic Ground. The line-up for the first two years was made up exclusively of jazz performers, but in 1963, several rhythm & blues acts were added to the bill, including the Rolling Stones, Georgie Fame, and Long John Baldry, and by 1965, such acts were in the majority, with jazz sessions reduced to Saturday and Sunday afternoons only. This format continued until 1967 when jazz was limited to just the Saturday afternoon session. By 1969, jazz had disappeared entirely from the line-up. In 1964, a Friday evening session was added to the existing weekend format. In 1966, the NJF Festival moved to the larger Windsor Racecourse. The following year a second stage (the Marquee Stage) was added, but when the festival was moved to Sunbury in 1968 it reverted to a single-stage format. The festival was held at Plumpton Racecourse in 1969 and 1970. 1970s After moving to Reading, the festival's line-up became primarily composed of progressive rock, blues, and hard rock during the early and mid 1970s, and then became the first music festival to incorporate punk rock and new wave in the late 1970s, when The Jam, Sham 69, and The Stranglers were among the headline acts. The festival's attempts to cater for both traditional rock acts and punk and new wave bands occasionally led to clashes between the two sets of fans at the end of the 1970s, though the festival gradually became known for focusing on heavy metal and rock acts. 1980s During the 1980s, the festival followed a similar format to that established in the late 1970s, with leading rock and heavy metal acts performing on the last two days, and a more varied line-up including punk and new wave bands on the opening day. Council ban In 1984 and 1985, the Conservative-run local council effectively banned the festival by designating the festival site for development and refusing to grant licences for any alternative sites in the Reading area. In 1984, many acts were already booked and tickets were on sale, with Marillion due to headline. The promoters tried in vain to find a new site but a proposed move to Lilford
