A bit of help, folks

Happy birthday to nicodemusrat and amelia_seyroon.

This next segment x-posted to filk.
What I need help with is a speech on filk: sounds a bit wierd, I know. I'm not allowed to use Wikipedia because of the credibility it causes, but I need at least 4 outside sources in this speech. I need to know:

• How do I define filk to mundane nuts who don't know anything about it?
• What are examples of said music genre that mundanity might know? (Wierd Al, etc.)
• What can be done with filk? (Burlesque, music video, literary works, CD accompaniment, etc)
• How do I wrap up an informative speech about everything covered and link it together? (This one, I can probably figure out on my own, but your suggestions would be welcome.)
• Finally, do I have your permission to site you as a source under the "testimonial" category?

Aside to jenkitty and members of Tres Gique: I wish to use some pictures for my presentation. Please send me an email or comment to work this out.
