Olivia Newton-John Hong Kong Coliseum One night only Two things to take from last night's Olivia Newton-John concert: don't buy her new album unless sickly sweet dedications to love and spirituality are your thing, and just how timeless is the music from Grease? Before launching into three classics from the 1978 movie in which she co-starred with John Travolta, the 58-year-old singer paid tribute to how much it meant to her. Summer Nights' 'tell me more, tell me more' was done playfully, with the crowd asked to split and do the boy and girl parts. One fan took it a bit far and let out a mournful scream that had Newton-John and the back-up male singer bursting into laughter. Newton-John received dozens of bouquets, cards and other dedications during the two-hour show. She looked remarkably well-preserved and managed many shimmies. She made light of her advancing years, pausing to sip tea and water and saying cheers each time. Given the age of most of the audience, the concert was appropriately sponsored by Memobrain, described by the announcer as 'a supplement for the central nervous system', and a book called Shocking Truth About Your Health. And a jazzy lounge version of her sexy 1981 hit Physical was described as 'age appropriate'. Xanadu, the title song from the 1980 movie also starring Newton-John, had fans tapping their feet, as did mid-1970s hit Please, Mr Please. By the mid-1980s Newton-John's career had peaked, but she had many hit singles under her belt by then which even the most casual, middle-aged fan today would have heard somewhere. Unfortunately, she combined many of these tunes into medleys and played far too many soppy ballads from her obscure and unremarkable recent albums, including the latest, Grace and Gratitude. 'I came to Hong Kong with my friends and can sing songs to you, how lucky am I?' she told the crowd. But she did them a slight disservice with her persistence in singing the forgettable. OK, she has an album to sell, but why squash classics together and only play three tracks from Grease. Perhaps this is harsh - and the fans' dedication and cheers at the end suggested that for them, anyway, she had delivered.
