Was That Nora Batty Singing?

Overview

Compo can't get over his suspicion of Nora's new lodger, Smiler. When he thinks he hears Nora singing a happy tune, he nearly goes to pieces. The trio tracks them around town, with Compo agonizing all the way. Meanwhile, Edie wants to go shopping at Huddersfield, but Wesley just wants to tinker with engines. Who do you suppose gets to have their way?
