Murphy wrote the lyrics and co-wrote the book for the musical
Reefer Madness. It was his third collaboration with writer-composer Dan Studney, but the first to be professionally produced. For the off-Broadway production of
Reefer Madness, Murphy was nominated for a
Drama Desk Award for "Outstanding Lyrics". Three staged readings of
Heathers: The Musical took place, with
Kristen Bell in the starring role; the creators hoped for a
regional production in 2010, to be followed by a
Broadway run in 2011. The musical then began an Off-Broadway run in March 2014 and closed in August 2014. The musical later had a run at
The Other Palace in London from June 2018 to August 2018, before transferring to the
Theatre Royal Haymarket for a run from September 2018 to November 2018. ==Personal life==
