The show was presented as a programme by a fictional TV network in Rutland, the smallest county in England. One running joke was that it was run on a shoestring. If the show parodied a topic, it would use names derivative of "Rutland". When Idle and Innes created a parody of the Beatles, Idle suggested "Rutles".
Innes was the musician/composer for the series and created songs with ideas on how they could be presented.
Innes came up with spoofing A Hard Day's Night. He had written "I Must Be In Love" which he realised sounded very "Beatley" and thought of the Rutles skit. He passed the idea to Idle, who had a separate idea about a boring TV documentary maker. They merged the ideas into one extended film shot for the TV show.
The Rutles had connections with The Beatles, the Bonzo Dog Doo-Dah Band and Monty Python. The Beatles were fans of the Bonzos: they featured them in the 1967 film Magical Mystery Tour and Paul McCartney (working with Gus Dudgeon under the alias Apollo C. Vermouth) had produced their 1968 hit single "I'm The Urban Spaceman". The Bonzos and members of the Python team worked together in the late 1960s on the TV comedy show Do Not Adjust Your Set. George Harrison was a Python fan as well as being involved in The Rutles film (see below), his company Handmade Films later took over production of Python film Life Of Brian after the original backers pulled out, fearing its subject was too controversial, as well as financing the two first solo films of ex-Python Terry Gilliam, Jabberwocky and Time Bandits.
In merchandising for the TV series, references were made to a Rutles album (Finchley Road) and a single ("Ticket To Rut"). In 1976, BBC Records produced The Rutland Weekend Songbook, an album containing 23 tracks including the Rutles songs "I Must Be In Love" and "The Children Of Rock And Roll" (later reworked as "Good Times Roll").
