Scooby Doo: Theme Song, By the light of the silvery moon, I can be scared with you

I was bored XD.
I just cut out some music parts from movies Scooby-Doo! The Mystery Begins, Scooby-Doo! Curse of the Lake Monster and put them together XD.
First clip: Theme song
Second clip: By the light of the silvery moon (the cutest scene I ever saw, shaggy singing to velma = sweet and sooo romantic XD)
Third clip: I can be scared with you (I just love that scene XD, they are so cool, funny and they are pretty good singers XD)
PS Sorry about my english XD
