From Take To The Sky fanzine issue 12 1998:
Tori's first single from Choirgirl, Spark, was accompanied by a video to promote it. The video was shot at Becky Falls, a public nature reserve in Dartmoor, Devon. Becky Falls is a 50 acre private woodland estate that has been a much-loved attraction since Victorian times when visitors would come to enjoy the peace and tranquillity of the beautiful secluded moorland valley with its abundance of flora and fauna. The video was directed by James Brown and depicts Tori as a victim of a kidnapping left tied and bound in the dense woodland. Trying to make her escape, she is pursued by her assailant until she manages to throw him off her trail. She finally reaches the open road, her wrists and ankles bleeding from the ties, when a car pulls up beside her. The female driver of the car and her passenger stop and stare at Tori, but soon depart the scene leaving Tori stranded, sinking to the gravel surface of the road.
