"Yes, a musical entitled The Train has for its theme that notorious contraceptive train which ran from Belfast to Dublin in 1971 and is to open next week in Dublin. I participated in that original stunt, but I have declined any further connection with the performance in question and chosen not to appear on any radio or television programme associated with it. I do not endorse Rough Magic's enterprise in turning this episode into a musical, because, for me, it is not the way to explain the historical context of birth control in Ireland - and elsewhere. I also feel that an experience which belongs to my life has been stolen. It is for me to tell my story, at least while I am alive, not others."
