When it rains down Shasta, you'll know

The story:

I always thought it was odd that Fleetwood Mac made a point of knowing when pop falls from the sky. It makes NO sense with the rest of song, but I just thought Fleetwood Mac got their turn to shine in weirdness/randomness like the rest of the bands. (No fan can deny that bands like the Beatles, Doors, Pink Floyd, and Cream are kinda weird) I finally got confused enough to look up the words on the Internet. When I found out what she's really saying, I let out a rather loud "Ah!" of relief that they weren't really singing about Shasta. And of course my older brother was there to ask what I was ah-ing about. Well, apparently I'm not the only one that hears "Shasta" in that line. When I told him about my mistake, he kinda scratched his head and asked me what the real words are. We had a good laugh after finding out that our version is WAY off!
