Barry buys a new saxophone from Auntie Wainwright. Glenda doesn't let him play indoors, so he has to find a spot outside to practice. The problem starts when Barry discovers in what type of case the saxophone comes in.Compo and an old local man start a competition to see which one of them is in better shape. The challenges include finding out who can climb a tree faster (problem is climbing down again), and who can go downhill faster, using Wesley's new invention.
