Darin Murphy has been studying and recreating the music of the Beatles for over thirty years.  He honed his musical and production skills in a series of "Fab Fourgeries", playing all the parts, producing, engineering and mastering (without the help of digital manipulation) half a dozen Beatles songs.     Murphy is known for his original music, a popular regional band with his sister, drumming for Robert Harrison-led "Cotton Mather", musical director and multi-instrumentalist for Texas party powerhouse SKYROCKET!, and a stint (approved by Yoko Ono) as understudy and one of the Lennons in Broadway musical "Lennon."    Now he joins WTWF for several shows in the following weeks and months in what we are referring to as "The summer of Darin Murphy."
