If there's a bustle in your head Joe
Don't be alarmed now
It's just a sprinkling from the Bake Queen

The story:

I�m 42 years old and I bet it�s not too much of an exaggeration to say that I have heard Stairway a million times in my life (so far�). I never was a Zeppelin fanatic; but at the same time, I can never remember a time when I didn�t like this particular song. I never really worried too much about the lyrics, but as a kid this lyric always perplexed me. I came to the conclusion that �Bake Queen� was a drug reference. I thought there had to be an association between �baking powder� and perhaps powder cocaine or angel dust, and that the lyric meant something like, �if you�re tripping, just enjoy it.� Worked for me.
A couple of years ago I finally, for the first time ever, looked up the lyrics on the Internet. I guess I wasn�t so surprised that I�d gotten them wrong, but I kind of liked mine more�
