Unfortunately, yes it has been removed along with several others.  Here is the official statment from GT:

Hi everyone, 

Unfortunately, we are unable to renew the license for a selection of our song lessons and we will be unpublishing some of our song lessons at the end of the month (March 31st). Please see the full list here: Songs Leaving Guitar Tricks.

Obtaining rights holder approvals for teaching songs online isn’t always an easy process, but we are proud to say that Guitar Tricks has always legally secured licenses with publishers. We have always honored the rights holders. Though we have an outstanding relationship with publishers, renewing the license for songs is not always guaranteed. 

Despite this loss, we still have hundreds of song lessons available, and we will continue to deliver new lessons each week. You will find all the newest lessons on the homepage under “Newest Lessons”.

While this might seem like a huge loss, we remain committed to our goal of being your best online learning resource for guitar. You gave us many great ideas in the recent user survey, and we’re working diligently to start implementing features that will enhance your learning experience. 
 
In addition to new releases each week, we will soon be launching a feedback feature, which will let you get direct feedback on your playing from an instructor. After submitting a video of your playing, you will get a feedback video privately shared with you from someone on our team.

Full Access users can also send questions directly to Anders Mouridsen, who teaches our Guitar Fundamentals course for beginners. He reads through all your comments and inquiries and posts a video based on your feedback each week through a feature we call Guitar Insider.

This song removal is not what we hoped for, but we are going to move forward with staying focused on what we can do improve how you learn with Guitar Tricks. 

We hope to deliver on that promise this year and we are so thankful for your continued support.

Mike
