From _A Critical Companion to James Joyce_ by Fargnoli and Gillespie I learnt the fascinating tidbit that the Circe episode not only was adapted to a play entitled _Ulysses in Night-town_ (directed by Burgess Meredith, of all people), but it was performed on Broadway in 1974:
> Because of its unique structure, the Circe episode has been seen as having the potential for a creative existence independent of the rest of the work. The best-known effort to exploit this feature occurred in 1958 when Burgess Meredith directed an off-Broadway production of _**Ulysses in Night-town**_ , a dramatization of this episode adapted for the stage by Marjorie Barkentin. Joyce’s old friend, the poet Padraic Colum, also assisted in the production. In 1974, the play was produced on Broadway.
Apart from this, Anthony Burgess wrote an operetta, _Blooms of Dublin_ , based on _Ulysses_. Scene 9 is his adaptation of the Circe chapter, although this is of course not a very faithful rendering of the text.
