His first play, The Fight of the Beeblebum, was a one-man show which Sebastian wrote and performed at the age of 16. It was seen for one night at The Questors, causing Alfred Emmet to write in TOAD, ‘Without doubt a major new talent has arrived among us.’ Subsequent plays, all produced at The Questors, were Shoeshop (1980), The Whirler (1982), Harry (1985), The Man Who Shot the Tiger (1987) and Hello Paris (1990, and revived 1992 for the Edinburgh Fringe).

Professional success began in 1996 with a production of The Lives of the Saints at the Old Red Lion, since when Sebastian has written extensively for radio, where his broadcast work has included an adaptation of Les Miserables; Arthur, a six-part retelling of the legend; and the original plays The Prettiest Girl in Texas, Stalingrad Kiss, The Orchid Grower and most recently The Influence. He is currently writing for Holby City on television.

Sebastian has also spent time working as a freelance drama teacher and director in Gloucestershire, and it was during this period that tonight’s two plays were created. Noah’s Point was commissioned by the Cheltenham Festival of Literature and Wycliffe School, and first performed there in 1995. A Labyrinth of Iron dates from 1997 and was first performed on commission from Cheltenham Ladies College by a cast from the school at the Edinburgh Fringe.
