Feldman became increasingly successful on television, particularly with "At Last the 1948 Show" (1967); he decided to concentrate on writing and performing on the screen and left the series. Took agreed to stay, and he was joined by Johnnie Mortimer, Brian Cooke and – for the first six episodes of the next series – Donald Webster. In September 1967 BBC radio was radically reorganised. The Home Service, Third Programme and Light Programme were abolished and replaced by four new national channels – Radio 1, 2, 3 and 4; "Round the Horne" moved from the Light Programme to Radio 2. The change came with reduced budgets. The Fraser Hayes Four and Eddie Braden and the Hornblowers were replaced with a small instrumental group led by Max Harris, and Pertwee was dropped from the programme. The cost fell from £601 a show in series 3 to £486 in series 4. That year's Christmas special was broadcast with the new line-up and writers.
