Example Input: Question: Who was the producer of the song Kelly appeared in the music video for with Vince Gill? Passage:MCA embarked on a big marketing campaign to tout Willis after she recorded her first album on the label, the 1990 album Well Travelled Love. MCA ensured that Willis was interviewed by several national magazines including unusual venues like Vogue and Mademoiselle. Her voice appeared in the 1991 Ridley Scott-produced movie Thelma and Louise, singing "Little Honey." Willis also had a small part in Tim Robbins’ 1992 film Bob Roberts. Willis appears as the young woman standing in a shallow stream in Dwight Yoakam's video of "A Thousand Miles from Nowhere," as well as a member of Vince Gill's "pickup band" in his Don't Let Our Love Start Slippin' Away video. She was also nominated for Top New Female Vocalist of the year at the 1993 ACM Awards along with Faith Hill and Lari White (Hill wound up winning the award). Despite of all the publicity and positive reviews from most reviewers, Well Travelled Love and Willis’s subsequent albums for MCA (Bang Bang in 1991 and Kelly Willis in 1993) sold modestly and received very little radio play. During this time, Willis felt uncomfortable with the way she was marketed by MCA. In 1994, MCA released Willis from her contract.
