Mainly active in the 1920s and 1930s, Campbell formed a songwriting and publishing team with fellow Brit Reginald Connelly (Campbell Connelly). They also collaborated with other songwriters.
Among their best known compositions are If I Had You (1928), Goodnight Sweetheart (1931) and Try A Little Tenderness (1933). They also wrote Midnight Stars And You and When The Organ Played At Twilight.
The duo of Connelly and Campbell sometimes used the pseudonym Irving King.
