iPhoto - VERY annoying Event slideshow music

[Karvel]

I've noticed in iPhoto '08 I can select an event and then press Play on my Apple Remote to give me a slideshow of just that selected Event. Is there any way I can change the godawful default guitar music to something from my iTunes library, without creating a separate Slideshow for all 39 or so Events?? I've already tried saving one Slideshow with the music I prefer to hear, to see if it could somehow make that the default Slideshow music (instead of the guitar song), but that doesn't seem to have worked!
