Although the pilot was produced in colour, the videotape was wiped in the 1970s leaving only a 16mm black-and-white film telerecording. In 2009 the pilot episode was restored to full colour using the colour recovery technique previously used for the Dad's Army episode Room at the Bottom. The restored version was first shown on BBC2 on January 1, 2010 as part of an Are You Being Served special night. (thetvdb.com)
