I was googling for information on Mike Bartlett specifically when I came across this interview with Paul Ashcroft and Ella Caldwell from Melbourne's Redstitch Actor's Theatre. Click on the link below the screencap to listen to the interview. It contains discussion of Mike Bartlett's work, the play and a scene from Act 1 performed by Ashcroft (Kenneth) and Caldwell (Sandra).
