Can anyone tell me the name of the incidental 音乐 used in the original scooby doo?

Hello Can anyone tell me the name of the incidental 音乐 used in the original scooby doo? It is used when ever the gang go and look for clues. It is also used for 标题 screen to the Scooby Doo 电影院 vol 1. I have also heard It was also used in the first two series.

And can anyone tell me where I might find a download of this 或者 video on youtube.

Much appreciated. I want it for my mobile phone.
