Livingstone was born in Dumbarton and started his career with Sinclair Swifts. He then moved to Artizan Thistle and Parkhead, before moving to Heart of Midlothian F.C. in the Scottish league. In 1900, he joined Sunderland, but he only played there for a season before moving to Celtic. He made 30 appearances and scored 12 goals in his time at Sunderland.
In 1902, he moved back to England, signing for Liverpool, and then Manchester City in 1903. He made 81 appearances for City, scoring 19 goals. He returned to Scotland in 1906, playing for Rangers for two years before transferring to Manchester United in 1908. He helped United win the 1911 league title, before retiring in 1914. He later worked under Bill Struth at Rangers as the first team trainer.
He is the only football player to-date that has played (and in fact scored) for both sides of the Old Firm, and for Manchester's finest.
