Well, 1st off my friend Meg is taking me to Tucson Saturday to see the Prairie Home Companion!!! Rad.
Ok now for the fact:
What is the "Ring of Fire"?
"There are about 600 active volcanoes on the face of the Earth. About half of them range along a belt of active volcanoes from the southern tip of South America north to Alaska, then west to Asia, and south through Japan, the Philippines, Indonesia and New Zealand. This is the "Ring of Fire", marking the boundary where the plates that cradle the Pacific Ocean meet those plates that hold the continents surround the ocean." from Don't Know Much About Geography.
Or.. you can say it's about LOVE.
"Although "Ring of Fire" sounds somewhat ominous, the term refers to falling in love - which is what June Carter was experiencing with Johnny Cash at the time. Some sources claim that June had seen the phrase, "Love is like a burning ring of fire," underlined in one of her uncle A. P. Carter's Elizabethan books of poetry. She worked with Kilgore on writing a song inspired by this phrase as she had seen her uncle do in the past. In the 2005 film, Walk the Line June is depicted as writing the song while agonizing over her feelings for Cash despite his drug addiction and alcoholism as she was driving home one evening. She had written: "There is no way to be in that kind of hell, no way to extinguish a flame that burns, burns, burns"." Wikipedia
