Question: What was the population of Sierra Leone the first year Fingland served as High Commissioner there? Passage 1:Following stints with the Dixie Melody Boys and Trav'lers Quartets, he joined J. D. Sumner and the Stamps Quartet in 1966. In 1972, he traveled briefly with the Blackwood Brothers, thereafter joining the Oak Ridge Boys as a member of The Mighty Oaks Band. Brown also played piano for Elvis Presley. He toured with the TCB Band for much of Presley's final two years and was a part of the 1976 "Jungle Room" recording sessions at Graceland. In 1979, he joined Emmylou Harris's backing band, the Hot Band, taking over for former Presley sideman Glen D. Hardin. Brown stayed with Harris until 1981. Later, he became a session musician in Nashville and toured with acts such as Rosanne Cash.
Passage 2:In 1964 Fingland was posted to Rhodesia as Deputy High Commissioner, and was still there in November 1965 when Ian Smith signed the Unilateral Declaration of Independence and a state of emergency. The British High Commissioner has to leave and Fingland stayed on as head of the residual mission until he was also expelled in 1966. He was then posted as High Commissioner to Sierra Leone 196669, an unstable time during which there were three military coups. After three years as assistant Under-Secretary of State at the Foreign and Commonwealth Office Fingland was posted as ambassador to Cuba 197275 and finally as High Commissioner to Kenya 197579, during which time he was also the UK Permanent Representative to the UN Environment Programme and briefly to the UN Centre for Human Settlements after it was established in 1978 (both UN organisations have their headquarters at Nairobi, Kenya).
Passage 3:After a short period in Scotland, Foster returned to English football with Doncaster Rovers where his opportunities were limited, though he had a spell with Ilkeston Town on loan. In 2001, he signed for Forest Green Rovers in the Conference National. He made well over 100 appearances for the club and had a spell as captain. He also appeared for Forest Green in the 2001 FA Trophy final at Villa Park but was on the losing side in a 1-0 defeat to Canvey Island. He was highly regarded amongst the supporters at The Lawn and many were sad to see him leave when he departed for Halifax Town in 2004. He made just under 100 league appearances for Halifax at The Shay before a move in 2007 to Oxford United.
