Problem: The Dubliners were an Irish folk band founded in Dublin in 1962. The band started off as The Ronnie Drew Ballad Group, named in honour of its founding member; they subsequently renamed themselves as The Dubliners. The group line-up saw many changes over their fifty-year career. However, the group's success was centered on lead singers Luke Kelly and Ronnie Drew.

The Dubliners became well known, not just in Ireland but also as pioneers for Irish folk in Europe and also (though less successful) in the United States. Their 1967 recordings of "Seven Drunken Nights" and "The Black Velvet Band" were released on the fledgling Major Minor label, and were heavily promoted on pirate radio station Radio Caroline. The result was that both records reached the top 20 in the UK pop charts. A third single, "Maids, When You're Young Never Wed an Old Man" reached number 43 in December 1967. It was their last UK hit single till they recorded with The Pogues in 1987. In 1974, Ronnie Drew decided to quit the band, to spend more time with his family. He was replaced with Jim McCann. Before joining the band McCann had a TV show in the early seventies called The McCann man. He is best known for his incarnations of "Carrickfergus", Makem's "Four Green Fields", and "Lord of the Dance". He stayed with the band until 1979 when he left to start a solo career; then Ronnie Drew rejoined the band. First Ronnie went to Norway to record two songs in the Norwegian language with the Norwegian band Bergeners. The Dubliners also gained popularity amongst famous musicians such as Bob Dylan, Roy Orbison, Jimi Hendrix and Pink Floyd's drummer Nick Mason, who were all self-proclaimed Dubliners fans. In the 1960s, The Dubliners sang rebel songs such as "The Old Alarm Clock", "The Foggy Dew" and "Off to Dublin in the Green". However, the conflict in Northern Ireland from 1969 onwards led them to drop most of these from their repertoire. They resumed performing such songs occasionally towards the end of their career. They have also recorded satirical protest songs against nuclear weapons such as The Button Pusher and Protect and Survive, feminist songs such as Don't Get Married, and socialist songs such as Joe Hill. On 8 February 2012, The Dubliners received a "Lifetime Achievement Award" at the 2012 BBC Radio 2 Folk Awards.

Problem: Fred McFeely Rogers (March 20, 1928 - February 27, 2003) was an American television personality, musician, puppeteer, writer, producer, and Presbyterian minister. Rogers was famous for creating, hosting and composing the theme music for the educational preschool television series Mister Rogers' Neighborhood (1968-2001), which featured his kind-hearted grandfatherly personality, and direct connection to his audiences. Originally trained and ordained as a minister, Rogers was displeased with the way television addressed children at the time, and made an effort to change this when he began to write for and perform on local Pittsburgh-area shows dedicated to youth. Rogers developed his own show on WQED in 1968, and it was distributed nationwide by Eastern Educational Television Network.

Rogers was born in Latrobe, Pennsylvania, 40 miles (65 km) southeast of Pittsburgh, to James and Nancy Rogers; he had one sister, Elaine. Early in life, he spent much of his free time with his maternal grandfather, Fred McFeely, who had an interest in music. He would often sing along as his mother would play the piano, and he himself began playing at five. He obtained a pilot's license while still in high school. Rogers graduated from Latrobe High School (1946). He studied at Dartmouth College (1946-48), then transferred to Rollins College in Winter Park, Florida, where he earned a B.A. in Music Composition in 1951. Rogers was also a trained general aviation pilot. At Rollins, he met Sara Joanne Byrd (born c. 1928), an Oakland, Florida, native; they married on June 9, 1952. They had two sons, James (b. 1959) and John (b. 1961). In 1963, Rogers graduated from Pittsburgh Theological Seminary and was ordained a minister in the United Presbyterian Church in the U.S.A. Rogers had an apartment in New York City and a summer home on Nantucket island in Massachusetts. Rogers was red-green color blind, swam every morning, and neither smoked nor drank. He was a vegetarian on ethical grounds, stating "I don't want to eat anything that has a mother." Despite recurring rumors, he never served in the military. His office at WQED Pittsburgh famously did not have a desk, only a sofa and armchairs, because Rogers thought a desk was "too much of a barrier".
