Hi, semi-submersible -
Check the FAQ index way at the top of this thread, and follow the link to Posting Lyrics. This link will also do the trick.
The operative word in the subject heading of a message is ADD and the song title (Lyr ADD if you have space).
I won't give an example - because every song in the Digital Tradition serves as an example. I know you're looking specifically for example on how to post parodies - but I don't want to get THAT specific and legalistic in the FAQ. The people who harvest songs for the Digital Tradition and the Mudcat Songbook, will make corrections if they're needed. Correct information is more important than correct format.
