TV screenings of this episode have Deborah Grant's nighttime "burn up" in the Porsche 911 loaned to her by boyfriend Geoff accompanied by an insipid cover version of Paul Simon's song "The Boxer"; culminating in Miss Grant being nicked by traffic cops on what is now the M25 in Buckinghamshire very close to the very tall arched bridge which carries the M40 over the M25. In all DVD issues of the series the musical part of Miss Grant's journey, including views of the aforementioned bridge are edited out - I can only assume that the DVD producers were unwilling to pay Paul Simon's songwriting royalty - a shame - because as any car enthusiast will know, The Porsche 911 employed an engine design known as a "boxer"
