Marshmallow songs

The kind that stick to your brain. Why is it, when I have not heard it or anything remotely like it, that I have had The Mamas & The Papas’ “Creeque Alley” stuck in my head all day? I’m not objecting, it’s just weird.
Blogger has been down every time I’ve tried it today (crushed by popularity since news of the sale to Google came out?), and I’ve still got that song stuck in my head. Maybe now it’ll move to yours.
“In a coffee house Sebastian sat
And after every number they’d pass the hat
McGuinn and McGuire just a-gettin’ higher
In L.A., you know where that’s at
And no one’s gettin’ fat except Mama Cass”
C’mon, you know the words!
