I created a placeholder and pasted your code into the HTML code (body) - this produced a textural link: "Larry Krause Music". Clicking on this link takes you to your Facebook page, but this is not a direct step/one-click process.

I tried to use the Facebook Page Plugin but as I cannot login, I could not test any widget for you.

Since I do not do Facebook, here's my relatively simple workaround:
1. Create an object on the "MouseOff" layer. This can be a photo, a graphic, a Facebook Logo, a 'whatever you want' placeholder.
2. Right mouse click on this object and select: "Web Properties..."
3. Select the "Link to Web or Email address" and paste in this URL: https://www.facebook.com/larrykrausemusic
Now when you click on your object (graphic/image/photo, etc.) you will go directly to your Facebook page.

I'm not sure what benefit the Facebook Widget Plugin provides, so I suspect someone who uses Facebook can add to this thread and demystify your widget issue.
