His first stage appearance was aged two weeks at the Theatre Royal, Birmingham when he was carried on in Dion Boucicault's play Arrah-na-Pogue.

By 1895, as Shaun Glenville-Luck he had joined the music hall entertainers, burlesque and sketch artists The Six Brothers Luck.

In 1907 with The Six Brothers Luck he toured the United States in their 'farcical sketch' 'The Demon of the Cellar' and a number of other variety acts.

[2] His stage appearances included: The Gay Lothario (1913); After The Girl and The Light Blues at the Gaiety Theatre, London (1914); the pantomime Humpty Dumpty with his wife Dorothy Ward at the Prince's Theatre, Bristol (1914–15); Razzle Dazzle at the Theatre Royal, Drury Lane (1916); tour of Happy Go Lucky with Dorothy Ward (1918); Sergeant O’Toole in Quality Street at the Shubert Theatre and Doc Sniffkins in The Whirl of New York at the Winter Garden Theatre in New York (1921);[9] The American critic Dorothy Parker was savage in her criticism of Ward's performance in Quality Street - and Glenville fared little better, with Parker writing: 'They have also imported a comedian named Shaun Glenville to add a touch of humor to the proceedings.

Various extant sheet music covers and other sources show that Glenville performed at least five other Godfrey songs on stage: 'When An Irishman Goes Fighting' (1914); 'Tommy's Learning French' (sung at a concert in France for the troops in June 1915 during World War I); 'Calling Me Home' (1922); 'My Little-Da-Monk' (1930); and 'It Takes An Irish Heart To Sing An Irish Song' (1932).

[2] The actor Roy Hudd related an occasion when Binnie Hale as principal boy was appearing as Jack in panto with Glenville as Mrs. Hubbard in Jack and the Beanstalk at the Theatre Royal, Drury Lane in 1936: 'One lunchtime Shaun arrived at the theatre twenty-five minutes late for the matinee - he had over imbibed.

You come in here twenty-five minutes late, stumbling around in a drunken stupor, smelling like a brewery, slurring your words with your flies undone – and I’ve got to call you Mother!

[1] He was survived by his wife and their son Peter Glenville (1913–96), an actor, film director and producer of Broadway shows.
