LONDON, May 29: Runaway Ukrainian dancer Sergei Polunin, more famous of late for his absences than his “arabesques”, showed up in London on Tuesday vowing to return in July to dance in a production of “Coppelia” with Moscow’s Stanislavsky Ballet. The Royal Ballet prodigy, dubbed the bad boy of dance, vanished from a London performance of “Midnight Express” in April less than a year after leaving Britain’s Royal Ballet in the lurch a week before he was due to dance for them.
