The Busby Babes were a group of Manchester United players, recruited and trained by the club's chief scout Joe Armstrong and assistant manager Jimmy Murphy, who progressed from the club's youth team into the first team under the management of the eponymous Matt Busby.

The Busby Babes were notable not only for being young and gifted, but for being developed by the club itself, rather than bought from other clubs, which was customary then, as now. The term, coined by Manchester Evening News journalist Frank Nicklin in 1951,usually refers to the players who won the league championship in seasons 1955–56 and 1956–57 with an average age of 21 and 22 respectively.

Eight of the players – Roger Byrne (28), Eddie Colman (21), Mark Jones (24), Duncan Edwards (21), Billy Whelan (22), Tommy Taylor (26), David Pegg (22) and Geoff Bent (25) – died as a result of the Munich air disaster in February 1958, while Jackie Blanchflower (24 on day of crash) (along with senior player Johnny Berry (31 on day of crash)) was injured to such an extent that he never played again.

Sir Alexander Matthew "Matt" Busby, CBE, KCSG (26 May 1909 – 20 January 1994) was a Scottish football player and manager, most noted for managing Manchester United between 1945 and 1969 and again for the second half of the 1970–1971 season. His manager records and longevity at the helm of Manchester United are only surpassed by Sir Alex Ferguson.

Before going into management, Busby was a player for two of Manchester United's greatest rivals, Manchester City and Liverpool. During his time at City, Busby played in two FA Cup Finals, winning one of them. After his playing career was interrupted by the Second World War, Busby was offered the job of assistant coach at Liverpool, but they were unwilling to give him the control over the team that he wanted and he took the vacant manager's job at Manchester United instead.

Born to Alexander and Nellie Busby in a two-roomed pitman's cottage in the mining village of Orbiston, Bellshill, North Lanarkshire, Busby was raised a practising Roman Catholic of Lithuanian ancestry. When he was born, Busby's mother was told by the doctor "A footballer has come into this house today". Busby's father – a miner – was killed by a German sniper during the First World War at the Battle of the Somme, while three of his uncles were killed in France with the Cameron Highlanders.

David Tennant (born David John McDonald; 18 April 1971) is a Scottish actor. In addition to his work in theatre, including a widely praised Hamlet, Tennant is best known for his role as the tenth incarnation of the Doctor in Doctor Who, along with the title role in the TV serial Casanova (2005) and as Barty Crouch, Jr., in the film Harry Potter and the Goblet of Fire (2005).

Tennant was born in Bathgate, West Lothian, Scotland, the son of Essdale Helen (née McLeod) and The Rev. Alexander McDonald (known to family and friends as Sandy McDonald). He grew up with his brother Blair and sister Karen in Ralston, Renfrewshire, where his father was the local Church of Scotland minister. Tennant's maternal great-grandparents, William and Agnes Blair, were staunch Protestants from Derry in Ulster, the northern province of Ireland, and were among the signatories of the Ulster Covenant in 1912; William was a member of the Grand Orange Lodge of Ireland. Tennant's maternal grandfather, footballer Archie McLeod, met William and Agnes's daughter Nellie while playing for Derry City.
