Question: How old was Wight when Smith died? Passage:Lyman Wight (May 9, 1796 – March 31, 1858) was an early leader in the Latter Day Saint movement. He was the leader of the Latter Day Saints in Daviess County, Missouri, in 1838. In 1841, he was ordained a member of the Quorum of the Twelve Apostles. After the death of Joseph Smith resulted in a succession crisis, Wight led his own break-off group of Latter Day Saints to Texas, where they created a settlement. While in Texas, Wight broke with the main body of the group led by Brigham Young. Wight was ordained president of his own church, but he later sided with the claims of William Smith, and eventually of Joseph Smith III. After his death, most of the "Wightites" (as members of this church were called) joined with the Reorganized Church of Jesus Christ of Latter Day Saints.

Question: What year did Ron Sweed begin his show on WKBF? Passage:Other programming on WKBF included a late-night weekend horror movie showcase hosted by Ron Sweed, whose on-air character was named The Ghoul. The Ghoul character was essentially a beatnik vampire, outfitted in a fright wig, goatee, lab coat, and a pair of sunglasses with one lens missing. It was patterned after the Ghoulardi character that was created by Ernie Anderson (with his permission), who was later to become the voice of the ABC network in the 1970s. While Anderson had no interest in doing so, he granted Sweed permission to don the costume. As WJW owned the rights to the name "Ghoulardi", the younger performer adopted the name "The Ghoul." Although WKBF has long since passed into broadcasting history, Sweed continued to make personal appearances on a fee-for-service basis in this guise until very late in life. WKBF also featured sports programming such as game telecasts from the World Football League and Cincinnati Royals NBA basketball, and harness racing.
