However, an abandoned steam roller and fairground organ trailer are blocking the route, which threatens to plunge the convoy into chaos.
In the church hall yard, Jones is showing off his newly restored butchers' van to the platoon.
The operation goes without further hitches until the men are collected and Mainwaring orders Jones to drive them back to the church hall.
En route, they find the road blocked by an abandoned steam roller and fairground organ trailer, and a note from its driver reveals that he has gone to get some coal.
Whilst doing so, Jones's van gets stuck in the mud and before long it is joined by Hodges' van, his motorbike and side-car (driven by the Verger, who is taking Mrs Fox to pick bluebells, much to the chagrin of Jones and the Verger's wife) and a coach carrying the Vicar, the Verger's wife and pensioners on a day trip (who take the opportunity to dance to the organ when Pike, who is trying to move the trailer, accidentally starts it up after unhitching it from the steam roller).
