There are not right now, but you can edit the plugin yourself to add another song (it is really easy trust me).
- Go to your list of plugins, scroll to Hello Dolly, and click edit.
- Now scroll down, and you will see the lyrics inside quotes.
- You can then paste your own lyrics there, but be sure not to delete the quotes on either end, and DO NOT touch any of the other code, or the plugin will not work.
Keep in mind that each sentence from the song has to be on its own line, or it will all appear at once. I did this myself so it will show quotes from the Big Lebowski, and it works fine. Good luck!
