Noted discussion about Mothers of Invention, Frank Zappa in shout box. Recalled how while performing at a Switzerland Casino a fan shot a flare which resulted in a fire that burned down the Casino and the Mothers equipment along with it. The group Deep Purple watched the fired from their hotel room, seeing the smoke from it spread across Lake Geneva. Band song writer it is said awoke from a dream a few days later, thing of the fire and the smoke on the water, hence the title "Smoke on the Water"
Another well know song few would not be aware of but on subject is Carly Simon's You're So Vain, the subject matter said to be Warren Beatty, We often hear many wonderful songs but often are not aware of why the written , their inspiration. It may be interesting for those being aware of some interesting origins/inspirations of popular songs to share them...
