Nelson performed more than 20 songs, including "On the Road Again" and "Always on My Mind," according to Consequence.

The appearance comes after Nelson canceled performances on his Outlaw Music Festival tour in late June due to illness.

"We regret to inform you that Willie Nelson is not feeling well and, per doctor's orders, has been advised to rest for the next four days. He is expected to make a quick recovery and join the Outlaw Music Festival tour next week," his team said June 21.

Nelson canceled another performance June 26.

The Outlaw Music Festival tour also features Bob Dylan , Robert Plant and Alison Krauss , John Mellencamp , and Billy Strings. The tour is scheduled to run through Sept. 20.
