This a video that I recorded from Nashville, TN at Edwin Warner Park during a tornado warning on September 6th, 2009 around 6PM. The sirens heard is an ATI HPSS-32 outdoor warning siren.
You will be able to see the funnel cloud around 2:30.
Here is the video:

Since I have started a chase team I will begin to upload more tornado videos from around Tennessee this upcoming Spring 2010.
Enjoy!
