Hey guys,

I haven't been around in, oh, 2 years or so...

Anyway, help me out! There's a local radio contest where you need to identify 10 clips from classic rock songs. I need help getting the very last one figured out.

Here is the link to the sound clip. I uploaded it to YouTube for you all to hear. The first static noise is figured out, but the second eerie "oooh" sound is still a mystery. Any help is greatly appreciated.
