The show also featured surreal dialogues with a "man at the window" of his studio, played by Willie Joss, who invariably referred to Murray by the name of "Chips".
The Glasgow Herald review of the play said, '"The most animated thing in the production was the energetic and multi-talented O’Sullivan charging on and off stage as he switched characters."
