 He was so excited that the first thing he did when he got home was write Laura Keene a letter stating that he was writing a play based on “The Collegians” and that he would have the first act to her by the end of the weekend.He told her that they should start the rehearsal/build process immediately and he would finish the play as they rehearsed, so basically, the definition of theatre on the fly (Morash 88).Thus, Dion took his play writing back to his Irish roots and “The Colleen Bawn” came to life and opened at the Laura Keene Theatre in May 1860 (Morash 89).
