Finish that tune!

I will state a lie from a song, and you have to finish it.

1 Scarecrow, scarecrow whats that you popping?
2 Generals gathered in their masses, Just like witches at black masses
3 These Words are my own, from my heart flown
4 Bring Sally up and Bring Sally Down
5 wake up, and face me,
6 You may say that I'm a dreamer, But I'm not the only one
7 Liar liar pants on fire ain't nobody getting no higher
8 Tasty, all aphrodisiacs, I got the munchies, weres the snack pack
