A sketch featuring The Two Ronnies impersonating DJ and presenter Jimmy Savile was subsequently edited from the BBC's 2012 DVD release "The Complete Collection" following posthumous revelations that Savile was the UK's most prolific sex offender.
The series was commissioned by the BBC's light entertainment executive Bill Cotton and BBC One controller Paul Fox after they were impressed by seeing Barker and Corbett give an impromptu performance together at the 1970 BAFTA awards while it was being delayed by technical problems.
Spike Milligan wrote the Phantom Raspberry Blower of Old London Town and David Jason provided them (which he claims to be a master at); years before, Milligan made out a treasured autograph to a then unknown Jason.
Known for being a perfectionist, Ronnie Barker monitored David Jason's raspberries carefully for volume, tone and duration whenever they did The Phantom Raspberry Blower sketch. Barker directed Jason in a sound-booth doing a raspberry version of the 1812 Overture. Jason joked in his autobiography that he would gladly re-stage it at the Royal Albert Hall, and considered "making farting noises into a microphone" one of the most profound jobs he's ever done for the BBC, and he's proud of his contribution to "that little moment of comic history". Barker and Jason became close friends, and Jason believed Barker very wise, and if he thought something was OK, that was good enough.
In 1979, Ronnie Barker and Ronnie Corbett took their families to Australia for a year, for job opportunities and to avoid the British Labour government's 83% top rate of income tax, which had been introduced in 1974.
For the "Star Trek" parody sketch, due to Ronnie Corbett's height, it was written in the script that Captain Kirk (Corbett) had gotten smaller due to an alien force and the alien force had caused Spock (Barker) to get big and fat. However, a special camera effect was set to up to make Corbett taller.
In the musical number sketch, Ronnie Barker and Ronnie Corbett would take a well known song and change the lyrics. One of the songs that the Two Ronnies would use and change the words to was the Nursery Ryme "This Old Man (Knick-knack Paddy-whack).
