Patches" in 1984. By this time, however, Tillis had built up a financial empire, thanks to investing in music publishing companies such as Sawgrass and Cedarwood. He also appeared in movies, including Cottonpickin' Chickenpickers (1967), W.W. and the Dixie Dancekings (1975), Smokey and the Bandit II (1980), The Cannonball Run (1981), The Cannonball Run II (1984), Beer for My Horses (2008), and comedy westerns The Villain (1979) and Uphill All the Way (1986), in which he starred with fellow country singer Roy Clark. In 1979, he acquired radio station KIXZ (AM) in Amarillo, Texas, from Sammons-Ruff Associates, which converted from Top 40 to country music and became a force in the Texas Panhandle region (the station is now known today as a News/Talk radio station). A short time later, Tillis acquired Amarillo, Texas, Rock FM station KYTX, which changed calls to KMML (a play on Tillis' stutter) (that station is now known today as KXSS-FM, a Top 40 radio station and is currently still a sister station to KIXZ). Still later, he operated WMML in Mobile, Alabama. All of his stations were sold after a time for a healthy return. He briefly signed with RCA Records, as well as Mercury Records, and later Curb Records in 1991. By this time, his chart success had faded. Later career and projects Following his heyday in the 1970s, Tillis remained a songwriter in the 1980s, writing hits for Ricky Skaggs and Randy Travis. He also wrote his autobiography called Stutterin' Boy. Tillis appeared as the television commercial spokesman for the fast-food restaurant chain Whataburger during the 1980s. He continued to record and have occasional hits through the decade, with his last top-10 hit coming in 1984 and his last top-40 country hit in 1988; like most country artists of the classic era, his recording career was dented by changes in the country music industry in the early 1990s. He also built a theater in Branson, Missouri, where he performed on a regular basis until 2002. In 1998, he teamed with Bobby Bare, Waylon Jennings, and Jerry Reed to form The Old Dogs. The group recorded a double album of songs penned entirely by Shel Silverstein. In July 1998, Old Dogs Volumes 1 and 2 were released on the Atlantic Records label. A companion video, as well as a Greatest Hits album (composed of previously released material by each individual artist), were also available.
