E&J Gallo Winery and Dick Clark Productions Inc. said they've teamed up to celebrate the millennium. Clark will appear in commercials for Gallo's Ballatore Sparkling Wine and use it to toast the new year on his "Dick Clark's New Year's Rockin' Eve" special. The Gallo campaign for the wine also includes in-store promotions and radio ads. Financial terms weren't disclosed. Gallo had a similar deal with Clark in 1998.
