I have added two audio files to my webpage, but only the second one can be played?

The webpage I am testing is:

http://aardvark101.googlepages.com/testofp...ng2flashstreams

The code used for the two audio streams is:

<embed src="http://www.jeroenwijering.com/embed/mediaplayer.swf" width="320" height="20" allowfullscreen="true" allowscriptaccess="always" flashvars="&file=churchbells.mp3&height=20&width=320"></p>

<embed src="http://www.jeroenwijering.com/embed/mediaplayer.swf" width="320" height="20" allowfullscreen="true" allowscriptaccess="always" flashvars="&file=pieces.mp3&height=20&width=320"></p>

The two audio files that should be playing are:

http://aardvark101.googlepages.com/churchbells.mp3
http://aardvark101.googlepages.com/pieces.mp3

Hope you can help!
Many thanks!
