Editing Reading and Leeds Festivals (section)

===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 [[Athletic Ground, Richmond|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.
