The legendary Frank Sinatra will be honored tonight on CBS with the special Sinatra 100: An All-Star GRAMMY Concert, and here's how to watch it live online.

Sinatra, who would have been 100 years old this year, will be paid tribute by a multitude of music's biggest stars. Sinatra 100 will feature musical performances of Sinatra's most famous songs and special tributes throughout.

"This show is an amazing journey through Frank Sinatra's music, cast with some of today's greatest artists," said Don Was, music director for the special. "In paying homage to Mr. Sinatra's music and treating his legacy with the utmost respect, most of the artists will sing arrangements as originally crafted for Mr. Sinatra by giants Don Costa, Gordon Jenkins, Quincy Jones, and Nelson Riddle. It's going to be an incredible show!"

Artists that are slated to perform at this concert include Tony Bennett, Garth Brooks, Zac Brown, Harry Connick, Jr., Celine Dion, Lady Gaga, Nick Jonas, Alicia Keys, John Legend, Adam Levine, Seth MacFarlane, Katharine McPhee, Sam Smith, Carrie Underwood, Usher and Trisha Yearwood.

Sinatra 100: An All-Star GRAMMY Concert airs tonight at 9/8c on CBS, but what if you're not near a TV at that time? You can still watch it online through a number of means.
