Lashing Out: Before jetting out of Sydney on Christmas Eve, the British pop singer Kim Wilde had time to catch a few rays at Bondi Beach. The peroxided blonde, whose latest single is a funky cover-version of the Diana Ross hit You Keep Me Hanging On, was camped right next to an agent of Today’s People. Conversation with her record-industry companions turned to other female pop stars. The most scorn was directed at Terri Nunn, the lead singer of the group Berlin, who has managed a number-one hit on most continents with the Top Gun theme song, Take My Breath Away. Wilde, the daughter of 1960s pop star Marty Wilde, has struggled to make the charts since her smash hit Kids in America.
