Campbell made a cameo appearance in the 1980 Clint Eastwood movie Any Which Way You Can, for which he recorded the title song. He gave up smoking in March 1992, and believed it improved his singing voice. In 1991, Campbell voiced Chanticleer the rooster in Don Bluth's live action/animated film Rock-a-Doodle. In 1999 he was featured on VH-1's Behind the Music, and on A&E Network's Biography and a PBS in concert special in 2001. He also appeared on a number of CMT programs, where he ranked among their Greatest Men of Country Music. He is credited with giving Alan Jackson his first big break after he recorded with Campbell's music publishing business in the early 1990s. Campbell also served as an inspiration to Keith Urban, who cites Campbell as a strong influence on his performing career. In 2005, Campbell was inducted into the Country Music Hall of Fame. It was announced in April 2008 that Campbell was returning to his signature label, Capitol, to release his new album, Meet Glen Campbell. The album was released on August 19. With this album, he branched off in a different musical direction, covering tracks from artists such as Travis, U2, Tom Petty and the Heartbreakers, Jackson Browne, and Foo Fighters. It was Campbell's first release on Capitol in over 15 years. Musicians from Cheap Trick and Jellyfish contributed to the album, as well. The first single, a cover of Green Day's "Good Riddance (Time of Your Life)", was released to radio in July 2008.
