The other day, I pulled over on the side of a road to help an elderly man whose 4wd had broken down. It appeared his radiator hose had split. I rang RACQ (Royal Automobile Club of Queensland) for him, flew around the corner and bought him a drink to keep him hydrated, and waited over an hour for RACQ to turn up with a new hose. Upon their arrival, they went to put the new part on, but found they had trouble. Lucky for me, I remembered my clarinet was in the boot, and went and grabbed the cork grease. We lubed up the hose, and it slipped on. Also, I know valve oil is getting at removing permanent pen from whiteboards. But are there any other uses for musical equipment???
