I've been listening to Bob Dylan's "Theme Time Radio Hour" on XM Radio Channel 2 (all day.) Bob is very funny. He just told the story of how coal miners used to take a caged canary into the coal mine with them. The proverbial "Canary in a coal mine." Canaries are very sensitive to the air supply and especially to the presence of Carbon Monoxide and Methane.

The miners would continue to work as long as they could hear the canary singing. If the canary stopped singing, the miners would then know it was time to get the hell out of the mine. If the canary starting singing any song by Air Supply, it was time to get the hell out of the mine... as fast as possible.

True story... thank you Mr. Dylan.
