Mystery flu virus fears have led two international musicians to postpone their Hong Kong show, with their Singapore promoter saying a visit here is 'too risky'. Flamenco guitar legend Miguel de la Bastide (below right) and jazz guitarist Martin Taylor (left) decided on Friday to cancel their April 24 'La Guitarra' performance at the Kowloon Jockey Club Auditorium. In an e-mail to La Guitarra's Hong Kong ground crew, Singaporean promoter Lim Chiah Lueng wrote: 'I have decided to re-schedule the show until a later period due to the outbreak of SARS in Hong Kong. It will be too risky to go ahead with this show until the situation gets clearer.' The guitarists are believed to be the first musicians to cancel a show due to fears about the mystery virus (also known as SARS, or severe acute respiratory syndrome), which has so far killed nine and hospitalised more than 90. A music industry source explained: 'Stage artists are especially vulnerable to airborne infections. They have a whole audience facing them, cheering them, breathing and sneezing at them. They also have to be aware that visiting one country with a declared health hazard might exclude them from visiting some other countries.'
