I recently discovered, via Spotify, a recording of a Duke Ellington performance which has not been made available before.
My best guess is that the recording is taken from Duke Ellington's appearance at XIV FESTIVAL INTERNAZIONALE DEL JAZZ which took place in Bolgogna, Italy in 1973 whilst Ellington was on his final European tour.
The festival continues, annually, to this day and the website says:
Nei giorni 8-9-10 novembre 1973 si tenne il XIV Festival Internazionale del Jazz che presentò interessanti gruppi di giovani: uno
italiano, la Big Band degli allievi del Conservatorio di Bologna diretta da
Ettore Ballotta, l’altro americano, “The Young Giants of Jazz” con Jimmy Owens,
Gary Burton, Cedar Walton e Roy Haynes. Furono inoltre presentati alcuni dei
miti che negli ultimi cinquant’anni avevano fatto grande e reso popolare il
jazz: la celebre orchestra di Duke Ellington, B.B. King, Sarah Vaughan, e, infine, Miles Davis.
Google translates this - very loosely - as:
'In the days 8-9-10 November 1973 was held the XIV International
Festival of Jazz which showed interesting groups of young people: one Italian,
the Big Band of the students of the Conservatory of Bologna, directed by Ettore
Ballotta, the other American, "The Young Giants of Jazz "with Jimmy
Owens, Gary Burton, Cedar Walton and Roy Haynes. They were also presented some
of the myths that over the past fifty years had made great and popularized the
jazz orchestra of the famous Duke Ellington, BB King, Sarah Vaughan, and finally,
Miles Davis.'
From the ever-reliable Ellingtonia discography, full details of the engagement are as follows:
