Catherine Anahid Berberian (July 4, 1925 – March 6, 1983) was an American mezzo-soprano and composer based in Italy.
 She interpreted contemporary avant-garde music composed, among others, by Luciano Berio, Bruno Maderna, John Cage, Henri Pousseur, Sylvano Bussotti, Darius Milhaud, Roman Haubenstock-Ramati, and Igor Stravinsky.
 She also interpreted works by Claudio Monteverdi, Heitor Villa-Lobos, Kurt Weill, Philipp Zu Eulenburg, arrangements of songs by The Beatles, and folk songs from several countries and cultures.
 As a composer, she wrote "Stripsody" (1966), in which she exploits her vocal technique using comic book sounds (onomatopoeia), and "Morsicat(h)y" (1969), a composition for the keyboard (with the right hand only) based on Morse code.

Marco Alessi is a fictional character from the Australian soap opera "Neighbours", played by Felice Arena.
 He made his first screen appearance as Marco during the episode broadcast on 5 May 1992.
 Marco was the first character introduced from the show's new Alessi family.
 He joined cousins and established characters Caroline Alessi (Gillian Blakeney) and Christina Robinson (Gayle Blakeney) in Ramsay Street.
 His parents Benito (George Spartels) and Cathy Alessi (Elspeth Ballantyne) with sibling Rick Alessi (Dan Falzon) soon followed.
 Arena was happy to portray an Italian character because it resembled himself - noting that characters of different ethnicity was rare on the show.
Beatles Arias is a 1967 LP recorded by American-born mezzo-soprano Cathy Berberian.

 The chamber arrangements were by Paul Boyer, and featured Guy Boyer on harpsichord and organ, with an unnamed French string quartet and a wind quintet.
 Berberian was inspired to create this album while singing along to her 13-year-old daughter's Beatles records.
