Question: What year was the character that Sweed patterned his character after created? 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.

Question: What is the middle name of the artist whose breakthrough album "Breakaway" Chantal wrote for? Passage:Canadian singer-songwriter, producer and pianist Chantal Kreviazuk has written, produced and performed on albums and tracks for a wide range recording artists, spanning from adult contemporary, pop, rock, to indie and hip-hop music. Initially, she began writing her own pop songs, especially after a 1994 motorcycle accident in Italy left her immobile for several months, and was signed by Sony Canada, where she released her debut album in June 1997. Chantal later released another album in 1999, before being featured in a range of soundtracks to films and TV series. Chantal began writing for other artists in 2001, where she co-wrote the song "Always and Forever" for Eleanor McCain. However, it was only in 2004 that Chantal started writing for more artists and received recognition as a songwriter. In the summer of 2003, Chantal met Canadian singer-songwriter Avril Lavigne, they formed a relationship of mutual respect and sisterhood, and eventually became songwriting partners. They co-wrote six songs for Lavigne's sophomore album, Under My Skin (2004): "Slipped Away," "Forgotten," "Together," "How Does It Feel," "He Wasn't" and "Who Knows." Kreviazuk described "He Wasn't" as "a super-fun, punk, screw-you-to-boys song," while "Forgotten" is a driving rock song inspired by similarly vibed music Lavigne was consumed with at the time. Also in 2004, Chantal co-wrote "Rich Girl", for Gwen Stefani's solo debut album, "Love. Angel. Music. Baby.", along with Dr. Dre, Jerry Bock, Mark Batson, Kara DioGuardi, Mike Elizondo, Sheldon Harnick and Eve. The song became a chart success, reaching the top-ten in over fifteen countries. Chantal also wrote for Kelly Clarkson's breakthrough album "Breakaway" in the end of 2004, sharing writing credits for the tracks "Where is Your Heart" and "Walk Away". In 2005, Chantal's co-writing song "He Wasn't" was released as Lavigne's final single from "Under My Skin", receiving a moderate impact on the charts and reaching only the top-forty in some countries. While in 2006, Clarkson's "Walk Away" was released as "Breakaway"'s final single, reaching the top-twenty in some countries.
