Guido and Maurizio De Angelis, also known as Oliver Onions,[2] are a prolific duo of Italian musicians, multi-instrumentalists, composers and singers, as well as television and film producers.

After a period of retirement from the music business in the 1990s and early 2000s, during which they moved into television and film production through their own company (named after themselves), they had a musical comeback thanks to a one-off concert event in Budapest, Hungary, billed as Oliver Onions Reunion Live Budapest and organized by local promoter Gábor Kóves mainly because of the duo's popularity in his homeland, itself due to the fact that Spencer & Hill films were hugely popular in the country during the Communist regime - and, according to Maurizio De Angelis's commentary on the show, still are.

Their soundtrack for the 1981 cartoon series Viva i Re Magi (previously released in 1979, in Spanish language, in Mexico and Argentina as Vivan los Reyes Magos), for which they wrote the story and the screenplay as well as the full score and all the songs (which they sang themselves) was also a local hit.

By the early 1990s the brothers had become disillusioned with the music business in general and in particular by their almost systematic lack of recognition as professional composers in Italy (although they were maintaining a solid fan base outside of their homeland).

During this period, the duo kept their musical output to the bare minimum, often limiting themselves to scores and soundtracks for their own television and cinematic productions, some of which were mainly composed and arranged by Maurizio (the duo's most musically active member) on his own, with his older brother Guido only providing basic melodic ideas;[4] they still managed to score sizeable audience hits in the area of production, with long running drama/romantic series such as Elisa di Rivombrosa and Incantesimo (among several others), broadcast for several seasons respectively by Mediaset and RAI.

Nine years later, in July 2016, Hungarian music promoter and impresario Gábor Kóves asked them to put on an Oliver Onions "reunion" and perform their greatest hits live on stage, backed by a rock band and a full orchestra, in a one-off concert event meant both as a celebration of their career and a tribute to their then-recently departed friend Bud Spencer.

Subsequently, it spawned a series of short but intense tours of Italy and Europe in the following years, all billed as Oliver Onions Is Still Our Name (parodying the title of their 1971 soundtrack for the second Terence Hill "Trinity" film).

In October 2021, the duo released Future Memorabilia, a greatest hits album including re-recorded versions of their best-known film and TV theme songs, some of them performed as duets with popular Italian and international stars - namely, former Thegiornalisti frontman Tommaso Paradiso, Roland Kaiser, Claudio Baglioni, Elio from Elio e le Storie Tese (adding his peculiar voice to the duo's popular "Firefighters Choir" from Watch Out, We're Mad!, a staple of their live repertoire) and Elhaida Dani.
