This weekend's Austin City Limits' showcase will be the 18th time American music legend Willie Nelson has been featured on the iconic show. In this exclusive clip from the upcoming episode Willie Nelson performs his classic "Funny How Time Slips Away."

Willie is staying busy. He and several of his big name friends were on hand a couple of weeks ago for the Willie Nelson tribute concert in Nashville. The Willie: Life & Songs of an American Outlaw, A Willie Nelson All-Star Concert Celebration is coming to your television set later this year. For a glimpse at that concert, click here to see Kris Kristofferson, Eric Church, and Willie perform the Kristofferson classic, “Me and Bobby McGee.”
