Born in Glasgow and raised in the city's Garthamlock neighbourhood,[2] Hood's older brother Jackie was also a footballer[9] who won the Liverpool Senior Cup while a reserve player at Everton[10] but had returned to Scotland and local Junior club St Roch's by the time his younger sibling was starting his career. Harry Hood initially attended school at St Aloysius' College where rugby union was the chosen sport.[9][2] Seeking a schoolboy appearance for Scotland, he moved to Holyrood Secondary School but was overlooked for the national schoolboy squad as he had already registered as a senior player at St Roch's.[9]
In summer 1962 he signed for Clyde, making his Scottish Division One debut in November of that year, aged 18.[11] Clyde were relegated to the second tier, but in the lower division Hood flourished, scoring 37 times from 45 appearances in all competitions during the 1963–64 season as the club gained promotion.[11] This good form continued into the next campaign and, after hesitating over a move to Celtic, the team he had supported in childhood,[9] he was transferred to English club Sunderland for a fee of £30,000 in November 1964.[11] In an early outing for the Roker Park club, Hood scored the only goal of the match against Manchester United.[8]
Hood missed the entire 1965–66 season because he pulled a double hernia in pre-season,[12] and after his recovery, he was in a group of players frozen out by manager Ian McColl.[12] Overall his spell in England was not particularly successful and in October 1966 he returned to Clyde for £13,000. The 1966–67 Scottish Division One season proved to be one of the best in the club's history as they finished in 3rd position, behind only European Cup winners Celtic and European Cup Winners' Cup finalists Rangers.[8]
In the 1967 close season Hood was a member of an unofficial Scotland national team which travelled to destinations including Israel, Australia and Canada, winning every match.[3] For many years the tour matches were not recognised as full internationals by the Scottish Football Association as full internationals, even though their opponents Israel and Australia did.[17][18][19] A BBC Sport article in June 2020 identified him as one of the best Scottish players to have never played a full international.[20] The SFA announced in October 2021 that some of the tour matches would be reclassified as full internationals[21] which meant that Hood was posthumously awarded an international cap.[21] – some match reports also credit him with a goal (against Israel) which is elsewhere assigned to Alex Ferguson.[22]
Later years
After his retirement from football, Hood ran a company (named Lisini, incorporating the names of his three children)[2] which owned and ran several public houses and restaurants in the Greater Glasgow area.[23][6] In 2012, he was inducted into the Clyde FC Hall of Fame.[8]
After a battle with cancer, Hood died around 6:30am on 26 May 2019, aged 74.[6]
