He also spent time with Cape Town City, Margate, Millwall, Houston Hurricane, Bulova SA and Andover.
[3] He returned to his old club to sign several players, including Steve Deere, Geoff Barnard and Blyth, to shore up the holes in the defence.
[7] As Palace struggled in the First Division, regularly finishing just above the relegation zone, Blyth became a permanent fixture in the defence alongside John McCormick.
[12] His effective partnership with Jim Steele was the mainstay of Saints' victorious FA Cup run of 1976, including beating his former club, Crystal Palace, in the semi-final.
[12] By the end of the 1976–77 season, six of the twelve players from Southampton's Cup-winning side had left the club; Blyth was the seventh after he had argued with McMenemy about breaking up the team too quickly.
[12] Blyth re-appeared in Palace's colours in November 1977 when Terry Venables signed him on loan, after Ian Evans, who had replaced him in 1974, had broken his leg.
[12] He later played for Houston Hurricane, before a spell in 1981 in Hong Kong with Bulova alongside Charlie George and Barry Daines.
