Toby Keith and Willie Nelson help send Stephen Colbert off into the sunset

Toby Keith Stephen Colbert final show

Comedian Stephen Colbert ended his popular Comedy Central show on Thursday evening by riding off into the night sky with President Lincoln and Alex Trebec in Santa's sleigh. Before he signed off, however, he was joined by a bunch of celebrities, including Toby Keith and Willie Nelson, for an emotional singalong. 

Go ahead and see if you can name all the famous folks in this video. 

Colbert will be taking over for David Letterman on CBS' Late Show sometime in 2015.
