input: Born in Rochester, New York, Hagen came from a working-class family of German descent. His parents were William and Louisa (Boelke) Hagen, his father worked as a millwright and blacksmith in Rochester's railroad-car shops. Walter was the second of William and Louisa's five children and the only son.  Hagen developed his golf game at the Country Club of Rochester, beginning as a caddie, and earned money to help support his family from pre-teen age. He earned ten cents per round and was occasionally tipped another five cents. Hagen played golf at every chance he got; caddie access to the course was limited to off-peak times, as it was elsewhere in the U.S. during that era. Hagen, with assistance from head professional Alfred Ricketts, gradually improved his golf skill to the stage where he was an expert player by his mid-teens, and was then hired by the club to give lessons to club members and to work in the pro shop. He made his top-class professional debut at age 19 at the 1912 Canadian Open, placing 11th, a good showing. Hagen followed up with a surprise 4th place showing at the 1913 U.S. Open at Brookline where he stated that he was treated badly by the other professionals who knew nothing about him. Hagen said "they pushed me off the tee and told me I could practice when they were through". He vowed to play in the 1914 U.S. Open and "win it", and he did exactly that.  Hagen was also very skilled at baseball, primarily as a pitcher and shortstop. He canceled a 1914 tryout for the Philadelphia Phillies in order to play in a golf tournament. Later that week, Hagen was the U.S. Open Champion, and his career was changed forever.

Problem: Background: The Nitty Gritty Dirt Band, an American country rock band, has existed in various forms since its founding in Long Beach, California in 1966. The group's membership has had at least a dozen changes over the years, including a period from 1976 to 1981 when the band performed and recorded as the Dirt Band. Constant members since the early times are singer-guitarist Jeff Hanna and drummer Jimmie Fadden. Multi-instrumentalist John McEuen was with the band from 1966 to 1986 and returned during 2001 departing once again in November 2017.
Context: The group was inactive for a 6-month period after Paint Your Wagon, then reformed with Jimmy Ibbotson replacing Chris Darrow. With William McEuen as producer and a renegotiated contract that gave the band more artistic freedom, the band recorded and released Uncle Charlie & His Dog Teddy, issued in 1970. Embracing a straight, traditional country and bluegrass sound, the album included the group's best-known singles; a cover version of Jerry Jeff Walker's "Mr. Bojangles", Michael Nesmith's "Some of Shelley's Blues", and four Kenny Loggins songs including "House at Pooh Corner", the first recordings of Loggins's songs. Their version of "Mr. Bojangles" became the group's first hit, peaking at #9 on Billboard's all genre Hot 100 chart, with an unusual 36 weeks on the charts.  The next album, All The Good Times, released during early 1972, had a similar style.  Nitty Gritty Dirt Band next sought to solidify its reputation as a country band when band member John McEuen asked Earl Scruggs if he would record with the group. Earl's "yes" was followed the next week when John asked Doc Watson the same question, receiving the same answer of 'yes'. This set in motion the further addition of other artists, and with the help of Earl and Louise Scruggs, they set to traveling to Nashville, Tennessee and recording what was to become a triple album, Will the Circle Be Unbroken with Nashville stalwarts Roy Acuff, Earl Scruggs, and Jimmy Martin, country pioneer Mother Maybelle Carter, folk-blues guitarist Doc Watson, Merle Travis, Norman Blake, and others. The title is from the song, "Will the Circle Be Unbroken (By and By)", as adapted by A. P. Carter, and reflects the album's theme of trying to tie together three generations of musicians: long-haired boys from California and older veterans of the middle American establishment. The track "I Saw the Light" with Acuff singing, was a success, and the album received two nominations for Grammy Award. Veteran fiddler Vassar Clements was introduced to a wider audience by the album and gave him a new career. The band also toured Japan twice soon after this period.  After the next album Les Thompson left the group, making the band a foursome. Stars & Stripes Forever was a live album that mixed old successes such as "Buy for Me the Rain" and "Mr. Bojangles" with Circle collaborations (fiddler Vassar Clements was a guest performer) and long storytelling spoken-word monologues. A studio album, Dream, was also released.  During July 1974, the band was among the headline acts at the Ozark Music Festival at the Missouri State Fairgrounds in Sedalia, Missouri. Some estimates put the crowd at 350,000 people, which would make this one of the largest music events in history. At another concert, the band opened for the rock band Aerosmith.
Question: What was the name of a song they wrote?
Answer: a cover version of Jerry Jeff Walker's "Mr. Bojangles",

Question: Alison Maria Krauss was born in Decatur, Illinois, to Fred and Louise Krauss. Her father was a German immigrant who came to the United States in 1952 and taught his native language. Her mother, of German and Italian descent, is the daughter of artists. Krauss grew up in the college town of Champaign, home to the University of Illinois at Urbana-Champaign.

Krauss made her recording debut in 1985 on the independent album, Different Strokes, featuring her brother Viktor Krauss, Swamp Weiss and Jim Hoiles. From the age of 12 she performed with bassist and songwriter John Pennell in a band called "Silver Rail", replacing their previous fiddler Andrea Zonn. Pennell later changed the band's name to Union Station after another band was discovered with the name Silver Rail. Pennell remains one of her favorite songwriters and wrote some of her early work including the popular "Every Time You Say Goodbye".  Later that year, she signed to Rounder Records, and in 1987, at 16, she released her debut album Too Late to Cry with Union Station as her backup band.  Krauss' debut solo album was quickly followed by her first group album with Union Station in 1989, Two Highways. The album includes the traditional tunes "Wild Bill Jones" and "Beaumont Rag", along with a bluegrass interpretation of The Allman Brothers' "Midnight Rider".  Krauss' contract with Rounder required her to alternate between releasing a solo album and an album with Union Station, and she released the solo album I've Got That Old Feeling in 1990. It was her first album to rise onto the Billboard charts, peaking in the top seventy-five on the country chart. The album also was a notable point in her career as she earned her first Grammy Award, the single "Steel Rails" was her first single tracked by Billboard, and the title single "I've Got That Old Feeling" was the first song for which she recorded a music video.
