At the post office, Granny Dryden tells Mrs. Goggins to tell Pat to go to her house. When Pat arrives, he goes into the attic and finds a tuba. He blows into it, giving Granny Dryden a fright. Pat then goes to Ted Glen's workshop. He gives a blow into the tuba and nearly gives Ted Glen a headache. Ted puts rags down the tuba and Pat goes to deliver more letters. But his van won't start. Ted takes Pat in his lorry to the post office so Pat can take the post bus. On the way, Pat blows into his tuba, frightning residents including P.C. Selby, who crashes into a dustbin on his bike.They reach the post office and Pat takes the bus. He practises his tuba again at Thompson Ground, which frightens Dorothy Thompson so much that she runs out of the farm house carrying a pitch fork. Pat decides it's probably best to practise somewhere where he can't frighten anyone. He stops by a tree to practice, where he naps and has a dream that he is a player in the band. After he wakes up, he blows into his tuba, not knowing that Miss Hubbard's garden is just behind the hedge, causing her to cut her tulips. Pat delivers the letters to Miss Hubbard, who asks about the noise. Pat says he doesn't know and leaves.That night, P.C. Selby goes out to make some inquires inquires. At the church, he and the Reverend Timms hear the noise of Pat's tuba and the two search the churchyard until they find him and discover that he is responsible for the strange noises. P.C. Selby asks what he's doing and realises that Pat is doing no harm. The Reverend suggests Pat should learn to play the tuba and Major Forbes can teach him. Soon, the village fete comes. Ted puts on the Reverend's record player, but it dies out. Granny Dryden becomes dissapointed. But Pat has an idea. The friends go to Miss Hubbards house and get her piano. Peter Fogg joins them. Then Pat and the other residents play in the band conducted by Major Forbes.
