A friend pointed me toward this, radio dramatization of Last Bus to Woodstock, so I thought I would direct you good people to it also. BBC Radio Four ran a radio strand called Saturday Night Theatre which was around for more than 50 years, having been launched in April 1943. The plays featured in the strand included stage plays, books adaptations and original dramatisations.
Original Broadcast Date: 15th June 1985.
Dramatized by Melville Jones. Inspector Morse is played by Andrew Burt (http://en.wikipedia.org/wiki/Andrew_Burt) and Lewis is played by Christopher Douglas, (http://en.wikipedia.org/wiki/Christopher_Douglas_%28British_actor%29).
So, here is the dramatisation of Colin Dexter’s, ‘Last Bus to Woodstock’ which I uploaded to my Morse YouTube channel. I hope you all enjoy it.
