SINGING duo the OperaBabes are at The Courtyard in Hereford on Saturday, May 19, as part of their first solo UK tour. Fresh from the release of their CD Renaissance, the glamorous duo have created a stage show featuring live music, a string quartet and striking costumes by Elizabeth Emanuel. Discovered busking in Covent Garden, the pair's break came singing at the 2001 FA Cup Final. Their first album sold a million copies and last year they became the first ever UK classical act to perform in Las Vegas. For tickets, priced £18, call 0870 1122330.
