Dankworth began a second career as a composer of film and television scores (often credited as "Johnny Dankworth"). Among his best-known credits are the original themes for two British TV programmes, The Avengers (used from 1961 to 1964) and Tomorrow's World. He also wrote the scores for the films Darling (1965) and Modesty Blaise and Morgan: A Suitable Case for Treatment (both 1966). He appeared in the film All Night Long (1962) with Dave Brubeck and Charles Mingus – playing himself – and played on the theme to the satirical BBC show The Frost Report in 1966. Dankworth was commissioned to write a piece for the 1967 Farnham Festival; and produced "Tom Sawyer's Saturday"; written for full orchestra and narrator: "a sort of 'Peter and the Wolf' which could be played by most reasonably competent youth orchestras". During this active period of recording, the Dankworth band nevertheless found time for frequent live appearances and radio shows, including tours in Britain and Europe with Nat King Cole, Sarah Vaughan and Gerry Mulligan, and concerts and radio performances with Lionel Hampton and Ella Fitzgerald. 1970s and 1980s Dankworth's friendship with Duke Ellington continued until the latter's death in 1974. He recorded an album of symphonic arrangements of many Ellington tunes featuring another Ellingtonian trumpet soloist Barry Lee Hall. Dankworth also retained his Ellington links by performing with the Ellington Orchestra under the direction of Duke's son, Mercer Ellington. Dankworth recorded various symphonic albums with Dizzy Gillespie and the Rochester Philharmonic Orchestra and others. Other jazz musicians with whom Dankworth performed include George Shearing, Toots Thielemans, Benny Goodman, Herbie Hancock, Hank Jones, Slam Stewart and Oscar Peterson. He always had an enthusiasm for jazz education, for many years running the Allmusic summer schools at the Stables in Wavendon near Milton Keynes, a theatre that Laine and he created in January 1970 in their back garden. From 1984 to 1986, Dankworth was professor of music at Gresham College, London, giving free public lectures. In 1982, Dankworth was awarded an Honorary Doctorate of Music from Berklee College of Music. Later work He appeared with Craig David on Later with Jools Holland on BBC Two. He set up his own record label, Qnotes, in 2003, to reissue some of his old recordings as well as new ones. They include a number with Julian Lloyd Webber, Dudley Moore and members of his family.
