When I Was A Girl, I Used To Scream And Shout, which received its New York premiere Off-Off-Broadway at the John Montgomery Theatre Aug. 8, is extending its run until Sept. 4 (past an original closing date of Aug. 29), with performances Monday through Friday at 8 PM.

Though this is the era of Spice Girls and Riot Grrrls, playwright Sharman MacDonald feels there's still room for a play about an era when young women had to be more circumspect about their views and sexuality.

When I Was A Girl, I Used To Scream And Shout tells of best friends growing up in 1950s-60s Scotland, coping with misconceptions about sex and one girl's repressive mother. Girl, which played at the Bush Theatre in 1984 and the Whitehall in 1996, won a London Evening Standard Award for most promising playwright.

Patricia Minskoff directs the drama, which stars Robin Morse (Six Degrees of Separation) and Roberta Maxwell (Lincoln Center's Our Town), alongside Juliet Pritner and Fred Koehler, who played the young boy, Chip, on TV's "Kate & Allie."
