Vintage Cliff Richard 40th anniversary Concert T-shirt. 1998 not only marked Cliff's 40th anniversary in the music industry, but was one of the most relentlessly busy years ever. After two months of concert touring in Australia and New Zealand, with guest artist Olivia Newton-John, he spent several weeks in Austria completing a new studio album which was released in the autumn. One of the summer highlights was participation in the tribute concert at Althorp for Diana Princess of Wales. The year ended with a four-week celebratory season of concerts in London's Royal Albert Hall. All tickets were sold within 48 hours of the box office opening, and a further twelve concerts were scheduled for early 1999. He has total sales of over 21.5 million singles in the United Kingdom and is the third-top-selling artist in UK Singles Chart history, only toped by the Beatles and Elvis Presley.
