As a result of the huge success of The Good Life, Bill Cotton, the controller of BBC 1, promised Richard Briers, Felicity Kendall, Penelope Keith and Paul Eddington shows of their own on the BBC when it ended in 1978. A year later, Paul Eddington and Penelope Keith both had huge success with their respective sitcoms Yes Minister and To The Manor Born. Felicity Kendall followed in 1981, with the less successful Solo, however Richard Briers had to wait six years before starring in Ever Decreasing Circles in 1984.
Barbara, I can't get my wellies off.
In a previous episode ("The Pagan Rite") Barbara was furious when she thought Tom had taken freelance work to help pay their bills, saying that their efforts in self-sufficiency should be all or nothing. But in "A Tug of the Forelock" she is the one who suggests they take on temporary work to afford petrol for their new vehicle. But the operative word here is, "temporary". Tom explains to Jerry that this was not, a "permanent state" and therefore not a breech of self-sufficiency. This principle was first presented by Tom in "The Pagan Rite" where he explains taking "one job for one purpose" is an acceptable exception.
