Problem: Gregory LeNoir Allman was born at Saint Thomas Hospital on December 8, 1947 in Nashville, Tennessee, to Willis Turner Allman (1918-1949) and Geraldine Robbins Allman (1917-2015). The couple had met during World War II in Raleigh, North Carolina, when Allman was on leave from the U.S. Army, and were later married. Their first child, Duane Allman, was born in Nashville in 1946. On December 26, 1949, Willis offered a hitchhiker a ride home and was subsequently shot and killed in Norfolk, Virginia.

Allman moved to Richmond Hill, Georgia, in 2000, purchasing five acres on the Belfast River. The last incarnation of the Allman Brothers Band was well-regarded among fans and the general public, and remained stable and productive. The band released their final studio album, Hittin' the Note (2003), to critical acclaim. Allman co-wrote many songs on the record with Haynes, and he regarded it as his favorite album by the group since their earliest days. The band continued to tour throughout the 2000s, remaining a top touring act, regularly attracting more than 20,000 fans. The decade closed with a successful fortieth anniversary celebration at the Beacon Theater, where the band would hold residencies most years during their reunion. In 2014, the Allman Brothers Band performed their final concerts, as Haynes and Derek Trucks desired to depart the group. Allman struggled with health problems during the last years of his life. He was diagnosed with hepatitis C in 2007, which he attributed to a dirty tattoo needle. By the next year, they had discovered three tumors within his liver. He went on a waiting list and after five months, he underwent a successful liver transplant in 2010. In 2011, Allman went public about his battle with hepatitis C. He headlined Merck and the American Liver Foundation's "Tune In to Hep C Campaign" to raise awareness and urge baby boomers to get tested and treated. As part of Tune In to Hep C, The Allman Brothers Band headlined a hepatitis C fundraiser and awareness concert at the Beacon Theater in New York. The concert raised $250,000 to benefit the National Viral Hepatitis Roundtable and the American Liver Foundation for education and awareness efforts. The National Viral Hepatitis Roundtable in October 2017 created the Gregg Allman Hepatitis C Leadership Award - an annual award to posthumously honor Allman and others who work on behalf of people living with hepatitis C. Michael Lehman, Allman's longtime manager, accepted the award on his behalf. Allman's seventh album, Low Country Blues, was produced by T-Bone Burnett. Upon its release in January 2011, it represented Allman's highest-ever chart peak in the U.S., debuting at number five. He promoted the album heavily in Europe, until he had to cancel the rest of the trip due to an upper respiratory infection. This led to lung surgery later in 2011, and rehab in 2012 for addiction following his treatments. That year, Allman released his memoir, My Cross to Bear, which was thirty years in the making. In 2014, a tribute concert was held celebrating his career; it was later released as All My Friends: Celebrating the Songs & Voice of Gregg Allman.

Question:
Guillermo Barros Schelotto (Spanish pronunciation: [gi'yermo 'baros eske'loto]; Italian: [ske'lotto] born 4 May 1973) is an Argentine former football forward, and the current manager of Boca Juniors. Barros Schelotto played 16 years of his professional career in the Argentine Primera Division (6 with Gimnasia y Esgrima La Plata and 10 with Boca Juniors). With these two teams, he won a total 17 official titles (one with Gimnasia and 16 with Boca). In 2007, Barros Schelotto left Boca Juniors for Columbus Crew in the Major League Soccer, therefore having his first experience outside his native country.
Born with a twin brother, Gustavo, Barros Schelotto was hence nicknamed El Mellizo ("the twin"). He started playing professionally at the end of 1991 with his hometown team Gimnasia y Esgrima de La Plata, where he scored 45 goals in 181 matches in five seasons and in 1993 won the AFA Centenario Cup. On 14 September 1997 he transferred to Primera Division Argentina powerhouse Boca Juniors, for whom he played for almost 10 years. He was considered an idol by Boca fans and in his later years at the club showed his experience whenever he stepped on the pitch. Barros Schelotto remains one of Boca's top scorers in international matches with 25 goals, just one goal behind former teammate Martin Palermo. In 1996, he was offered to play for River Plate, but after club icon Enzo Francescoli was not happy with the potential signing, the deal collapsed. In mid-1997, Boca Juniors showed interest for him and his brother Gustavo. It was like that that Barros Schelotto twins arrived to Boca teaming up to a former rival: Martin Palermo, Gimnasia's archrival Estudiantes de La Plata former player. The three of them were repeatedly recommended to Boca by Diego Maradona, who was playing his last season for the Buenos Aires team, retiring on October the same year. Once in Boca, he made his debut as a substitute for Claudio Caniggia, scoring on 14 September 1997 against Newell's Old Boys in a 2-1 victory. With Carlos Bianchi as Boca Juniors' coach, Barros Schelotto got his traditional 7 shirt and kept it until 2006-07 season. He and former rival Martin Palermo became a successful attacking duo, who highly contributed in the 1998-99 title-winning season. He missed the 2001 and 2003 clubs international achievements due to injuries. In 2003, he was a key piece in the winning Copa Libertadores side, with his peak performance at the Round of 16 match against Brazilian team Paysandu, where he scored a hat-trick and assisted Marcelo Delgado's goal. In the second half of 2003 he again suffered from injuries and could only play for 46 minutes in the Copa Intercontinental winning match against AC Milan, when he replaced Carlos Tevez. With Alfio Basile as Boca coach, his participation in the first team was gradually lowering. He even was out of some first team matches and had to play for the second team to maintain his performance level. He scored 87 goals in 302 games for Boca Juniors.
