Singer Bonnie Tyler cancelled a press conference on Friday (17May13) over fears she would lose her voice ahead of her performance on Saturday's (18May13) Eurovision Song Contest. The Total Eclipse of the Heart hitmaker is representing Britain in the singing competition, and will take to the stage in Malmo, Sweden to perform Believe In Me, a track written for her by Desmond Child. However, Tyler's gruelling promotional schedule has left her her voice "hoarse" and she decided against staging a final press conference before the TV contest. A spokesperson for the BBC, which airs the programme in the U.K., tells Britain's Daily Star newspaper, "Since she arrived in Sweden, Bonnie has done so much press and in rehearsals she has really been going for it. "As a result, her voice has become hoarse. It was decided it would be best for Bonnie to rest it ahead of the live show." In one of her last interviews before the contest, Tyler admitted to The Sun that she was shunning booze ahead of the showdown, saying, "I am not drinking until after the contest. But when I've done my performance I am going to have a nice couple of glasses of red wine. If there is a party afterwards, I'll be there, darling." The singer also revealed that she plans on wearing her late mum Elsie's ring when she performs as a good luck charm. She added, "I feel like she is looking down on me. Whenever I do a performance I always think of my mother and father. I will know I have got her ring on and I'll know she is with me all the way. She will be singing along with me."
