text: Like the vast majority of Bill Shankly's first great team, St John was at his peak during the mid-1960s. He continued to play regularly during the later 1960s, mainly playing in a deeper position. As he entered his thirties his form and fitness began to dip, and he was eventually dropped from the team by Shankly. St John was a reserve team player in 1970–71, and he left Liverpool on 25 August 1971, after playing 425 games and scoring 118 goals for the club.
  Coventry City and Tranmere Rovers
  St John played for South African club Hellenic during the middle of 1971. After his return to England in August 1971, he was transferred to Coventry City. After a short spell with Tranmere Rovers, then managed by Ron Yeats, he retired from playing football in 1973.
  International career
  St John was selected to play for Scotland 21 times, making his debut in a 3–2 friendly victory against West Germany at Hampden Park on 6 May 1959. The first of his 9 international goals came a year later, again at Hampden, but this time in a 3–2 friendly defeat at the hands of Poland on 4 May 1960. He scored twice in a 1962 FIFA World Cup qualification playoff match against Czechoslovakia in November 1961, but Scotland lost 4–2 after extra time and did not qualify for the World Cup finals.
