 The publication, written by Prof David Birch and edited by A/P Kirpal Singh, was an extensive investigation into Sharma's development as a writer; the themes and issues he grapples with; as well as his vision and practice of theatre within and outside his work at The Necessary Stage.While "Interlogue" itself was not published by The Necessary Stage, the company assisted with the provision of archival material for Prof Birch's research.In 2010, The Necessary Stage published a new anthology of Haresh's plays entitled "Trilogy", including the scripts and production notes of three award-winning works, "Fundamentally Happy, Good People" and "Gemuk Girls".
