about". The revised series continued to be broadcast in the US. The episodes with Linda Thorson as King proved to be highly rated in Europe and the UK. However, in the US, the ABC network chose to air it opposite the number-one show in the country at the time, Rowan and Martin's Laugh-In. Steed and King could not compete, and the show was cancelled in the US. Without this vital commercial backing, production could not continue in Britain either, and the series ended in May 1969. The final scene of the final episode ("Bizarre") has Steed and King, champagne glasses in hand, accidentally launching themselves into orbit aboard a rocket, as Mother breaks the fourth wall and says to the audience "They'll be back!", before adding in shock "They're unchaperoned up there!" Cast Patrick Macnee as John Steed (Series 1–6) Ian Hendry as Dr David Keel (Series 1) Honor Blackman as Cathy Gale (Series 2–3) Jon Rollason as Dr Martin King (Series 2) Julie Stevens as Venus Smith (Series 2) Diana Rigg as Emma Peel (Series 4–5) Linda Thorson as Tara King (Series 6) Production Music The 1961 series featured a jazz-influenced theme by John Dankworth. Library music was used sparsely as a soundtrack, sometimes with variations based on the main theme. Dankworth's theme music was reworked for the third series. Dankworth's first theme was recorded on the Columbia label, on a 45rpm single, and a new recording, similar to the reworked television theme was issued on Fontana in 1963. A very faithful cover version was released by Johnny Gregory. When Rigg joined the series in 1965, the opening credits of the series were redesigned and new theme music by Laurie Johnson was introduced. This was based on a previously released title on LP, called "The Shake" (which capitalised on "The Shake" dance craze of the '60s). For the colour series (1967), a percussion section was added to accompany the new teaser sequence at the start of each episode. Johnson re-scored the theme when Linda Thorson joined the series, adding a counter-melody on trumpet, based on the leitmotif for Tara King from the final Rigg episode "The Forget-Me-Knot". The new theme debuted in the closing titles of the episode "The Forget-Me-Knot", which introduced Thorson. It was altogether more dynamic, and included a much more frenetic percussion section, for the revised teaser sequence. Importantly, the filmed episodes contained specially composed scores
