Problem: Robert Swan Mueller III (; born August 7, 1944) is an American attorney who served as the sixth Director of the Federal Bureau of Investigation from 2001 to 2013. A Republican, he was appointed by President George W. Bush; President Barack Obama gave his original ten-year term a two-year extension, making him the longest-serving FBI director since J. Edgar Hoover. He is currently head of the Special Counsel investigation of Russian interference in the 2016 United States elections and related matters. A graduate of Princeton University, Mueller served as a Marine Corps officer during the Vietnam War, receiving the Bronze Star Medal with Combat "V" for heroism and the Purple Heart Medal.

Mueller was accepted for officer training in the United States Marine Corps in 1968, attending training at Parris Island, Officer Candidate School, Army Ranger School, and Army jump school. In July 1968, he was sent to South Vietnam, where he served as a rifle platoon leader with Second Platoon, H Company, 2nd Battalion, 4th Marines, 3rd Marine Division. In December 1968, he earned the Bronze Star with 'V' distinction for combat valor for rescuing a wounded Marine under enemy fire during an ambush that saw half of his platoon become casualties. In April 1969, he received an enemy gunshot wound in the thigh, recovered, and returned to lead his platoon until June 1969. For his service in and during the Vietnam War, his military decorations and awards include: the Bronze Star Medal with Combat "V", Purple Heart Medal, two Navy and Marine Corps Commendation Medals with Combat "V", Combat Action Ribbon, National Defense Service Medal, Vietnam Service Medal with three service stars, Republic of Vietnam Gallantry Cross, Republic of Vietnam Campaign Medal, and Parachutist Badge. Mueller eventually became aide-de-camp to 3rd Marine Division's commanding general, then-Major General William K. Jones, where he "significantly contributed to the rapport" Jones had with other officers, according to one report. Reflecting on his service in the Vietnam War, Mueller said, "I consider myself exceptionally lucky to have made it out of Vietnam. There were many--many--who did not. And perhaps because I did survive Vietnam, I have always felt compelled to contribute." After returning from Vietnam, Mueller was briefly stationed at Henderson Hall, before leaving active-duty service in August 1970. He was inducted into the Ranger Hall of Fame in 2004.

Problem: The Undertones are a punk rock/new wave band formed in Derry, Northern Ireland, in 1974. From 1975 to 1983, the Undertones consisted of Feargal Sharkey (vocals), John O'Neill (rhythm guitar, vocals), Damian O'Neill (lead guitar, vocals), Michael Bradley (bass, vocals) and Billy Doherty (drums). Much of the earlier Undertones material drew influence from punk rock and new wave; the Undertones also incorporated elements of rock, glam rock and post-punk into material released after 1979, before citing soul and Motown as the influence for the material released upon their final album. The Undertones released thirteen singles and four studio albums between 1978 and 1983 before Sharkey announced his intention to leave the band in May 1983, citing musical differences as the reason for the break up.

The Undertones formed in Derry, Northern Ireland in 1974. The band members were five friends from Creggan and the Bogside, who originally drew inspiration from such artists as the Beatles, Small Faces and Lindisfarne. The band initially rehearsed cover versions at the home of the guitarists, brothers John and Vincent O'Neill, and in the shed of a neighbour. (In early 1976, before the band had played gigs at any venues, Vincent O'Neill left the band; being replaced by his younger brother Damian.) Beginning in February 1976 the group, at this stage still unnamed, began playing gigs at various minor local venues, including schools, parish halls and Scout huts, where the band's lead singer, Feargal Sharkey, was a local Scout leader. Sharkey was also responsible for giving the band their first name: at the introduction to a gig at Saint Joseph's Secondary School in Derry on 16 March 1976, Feargal Sharkey was asked the name of the band and quickly replied "The Hot Rods". At a later gig, Sharkey named the band "Little Feat": another name already used by another group. Later that year, drummer Billy Doherty proposed an alternate name for the group: The Undertones, which Doherty had discovered in a history book. The other members of the band agreed to the proposal. With the arrival of punk rock in late 1976, the artistic focus of the band changed. Artists such as the Adverts, Sex Pistols, the Buzzcocks and, particularly, the Ramones became major influences on the Undertones. In addition to being a scout leader, Feargal Sharkey worked as a television repairman and delivery man. The van which Sharkey drove in this employment was used by the Undertones to transport their equipment to and from various venues.
