This feel-good fifties musical has been a bit hit on tour, in Europe and now back in London. Sandy and Danny spend a summer in love, but think they will never meet again. That is, until Sandy unexpectedly joins Danny's high school to find that he is not exactly how she remembers him. Most famous for the 1979 film version starring John Travolta and Olivia Newton-John, Grease has become a firm family favorite, not least for its songs, which include "Summer Lovin'," and "There Are Worse Things I Could Do."
