In 1993 and 1997, the Regency Playhouse promoted the play Lost Soul with ads on double-decker buses in London, suggesting that it had a four-year run at the theatre, or was produced on two separate occasions. In the summer of 1997, an adapted production of Romeo and Juliet, William Shakespeare's classic tragedy, was staged at the Regency Playhouse by the Carneiro Players. This production was directed and designed by M. Carneiro and featured music by Luca Caruso and Alice Tolipan.
