Problem: Lehrer was born in 1928 to a Jewish family and grew up in Manhattan's Upper East Side. Although he was raised Jewish, Lehrer became an agnostic. He began studying classical piano at the age of seven, but was more interested in the popular music of the age. Eventually, his mother also sent him to a popular-music piano teacher.

Lehrer earned his Bachelor of Arts in mathematics (magna cum laude) from Harvard University in 1946. He received his MA degree the next year, and was inducted into Phi Beta Kappa. He taught classes at MIT, Harvard, Wellesley, and the University of California, Santa Cruz. He remained in Harvard's doctoral program for several years, taking time out for his musical career and to work as a researcher at the Los Alamos Scientific Laboratory. He was drafted into the U.S. Army from 1955 to 1957, working at the National Security Agency(NSA). (Lehrer has stated that he invented the Jell-O Shot during this time, as a means of circumventing liquor restrictions.) These experiences became fodder for songs, e.g., "The Wild West Is Where I Want to Be" and "It Makes a Fellow Proud to Be a Soldier". Interestingly, it was many years before Lehrer publicly revealed having been assigned to the NSA, since the mere 'fact-of' its existence was classified at the time: this left him in the interesting position of implicitly using nuclear weapons work as as cover story for something more sensitive. Despite holding a master's degree in an era when American conscripts often lacked a high school diploma, Lehrer served as an enlisted soldier, achieving the rank of Specialist Third Class (later retitled "Specialist-4" and currently "Specialist"), which he described as being a "corporal without portfolio." In 1960, Lehrer returned to full-time studies at Harvard, but in 1965 gave up on his mathematical dissertation about the subject of modes in statistics, after working on it intermittently for 15 years. From 1962, he taught in the political science department at the Massachusetts Institute of Technology (MIT). In 1972, he joined the faculty of the University of California, Santa Cruz, teaching an introductory course entitled "The Nature of Mathematics" to liberal arts majors--"Math for Tenors", according to Lehrer. He also taught a class in musical theater. He occasionally performed songs in his lectures, primarily those relating to the topic. In 2001, Lehrer taught his last mathematics class (on the topic of infinity) and retired from academia. He has remained in the area, and in 2003 said he still "hangs out" around the University of California, Santa Cruz.

Problem: Kath was born to Raymond Elmer "Ray" (1912-2003) and Evelyn Meline Haugen Kath (1916-1982) on January 31, 1946, in Chicago, Illinois. He has an older brother, Rod Kath. He was raised in the Norwood Park neighborhood of Chicago.

Kath was regarded as Chicago's bandleader and best soloist; and his vocal, jazz and hard rock influences are regarded as integral to the band's early sound. He has been praised for his guitar skills and described by rock author Corbin Reiff as "one of the most criminally underrated guitarists to have ever set finger to fretboard". The group's first album, The Chicago Transit Authority, released in 1969, includes Kath's composition "Introduction," described as "Terry's masterpiece" by later Chicago guitarist Dawayne Bailey. The song displays many varied musical styles, including jazz, blues, salsa, rock and roll, acid rock, and pop. The same debut album includes an instrumental guitar piece titled "Free Form Guitar", which consisted largely of feedback and heavy use of the Stratocaster's tremolo arm. The album liner notes indicate that the nearly seven-minute piece was recorded live in the studio in one take, using only a Fender Dual Showman amplifier pre-amped with a Bogen Challenger P.A. amp. The guitar's neck was held together with a radiator hose clamp. The song "Beginnings" includes acoustic rhythm guitar by Kath. For the group's second album, Kath contributed an extended guitar solo on "25 or 6 to 4", which became a live favorite. The same album saw Kath collaborate with orchestral arranger Peter Matz on the four-part suite "Memories of Love", singing the lead vocal. Kath wrote at least one song and contributed at least one lead vocal to every Chicago album released during his lifetime. While 1976's Chicago X is best known for Cetera's number one hit, "If You Leave Me Now", Kath's "Once or Twice" showed he was still writing and recording rock material. He continued this style on the following year's Chicago XI, contributing the funky "Mississippi Delta City Blues" and the aggressive "Takin' It on Uptown", which counterbalanced some of the material other members were producing. After his death, to memorialize Kath and to commemorate the resumption of Chicago, the band composed and published the song "Alive Again" on its first album without him, Hot Streets. Also in Kath's honor, they later published the song "Feel the Spirit".

Problem: Hilltop Hoods are an Australian hip hop group that formed in 1994 in Blackwood, Adelaide, South Australia. The group was founded by Suffa (Matthew David Lambert) and MC Pressure (Daniel Howe Smith), who were joined by DJ Debris (Barry John M. Francis) after fellow founder, DJ Next (Ben John Hare), left in 1999. The group released its first extended play, Back

In 2006 Hilltop Hoods were nominated for five ARIA Awards - the first ever for an Australian hip hop group - winning in two categories: 'Best Urban Release' and 'Best Independent Release'. The following year they won 'Best Urban Release' at the ARIA Awards for The Hard Road: Restrung. The album was also nominated for 'Best Independent Release' and 'Best Cover Art' by John Engelhardt. The DVD City of Light was nominated as 'Best Music DVD' at the 2008 ARIA awards. At the 2009 ARIA Awards they won 'Best Urban Album' for a third time - for State of the Art and DJ Debris won an award for 'Engineer of the Year' for his work on that album. At the ARIA Music Awards of 2012, Hilltop Hoods won its fourth award in the 'Best Urban Album' category for Drinking from the Sun; as of November 2012, the group has won six awards from twenty nominations. At the 2012 ARIA Awards, established Aboriginal Australian band, Yothu Yindu, was inducted into the Hall of Fame. A photograph of Suffa holding the award in the presence of the band was posted on the Hilltop Hoods' Instagram profile, accompanied by the following comment: "A memory I'll take to the grave. Meeting Yothu Yindi and having them let me hold their Hall of Fame ARIA. What a beautiful induction." The band was nominated in three ARIA categories in 2014: Best Group, Best Urban Album and Engineer Of The Year. In an October 2014 radio interview, Smith said that the band does not expect to win an award, but wishes the best for the winners; however, the Best Urban Album award was given to the band on 26 November 2014, providing the band with their seventh ARIA award.
