Bruno Heinz Jaja
Fictional composer, likely German, whose works were performed at two Hoffnung Festivals, a British music festival featuring parodies of classical music.
The 1956 concert featured a duet from his comic opera The Barber of Darmstadt, really by Humphrey Searle.
The 1961 concert featured "Punkt Contrapunkt," a parody of avant-garde pieces of the time.
Jaja's name is a parody of real avant-garde Italian composer Luigi Nono
