Jackson gave Brown the 1966 Cadillac El Dorado convertible as a thank-you for including him on the hit, "As She's Walking Away," just hours before the band's concert in Nashville Wednesday -- then put in a surprise appearance at concert to sing the Grammy-nominated song, The (Nashville) Tennessean reported.
"I think Zac is one of the coolest new talents to come along and he's a Georgia boy like me," Jackson said in a release about the Caddy. "It was an honor to be on his record."
After "As She's Walking Away" ended, Brown said, "That's how you do it right there. That's a legend of county music right there in our presence, people."
