The end of an era is near.  As you know, after 22 years on the job, Jay Leno will give up the host chair of the "Tonight Show" on February 6.  Blake Shelton & Lyle Lovett are slated for appearances the final week...and superstar Garth Brooks is scheduled for the last night.  Another final-night guest will be Billy Crystal, who was Leno's first guest in 1992.  Jimmy Fallon will take over Friday, 2/7.

Check out Garth on the "Tonight Show" Thursday, 2/6!
