It's Robert's birthday - he is turning 35 and his closest friends are throwing him a surprise party. Witty and well-liked, living in the heart of New York and dating three gorgeous women, Robert has it all … so why can’t he blow out the candles on his birthday cake and make a wish? Each attempt triggers the next turn in Sondheim’s beloved ‘concept musical’. Company examines the affairs of the heart: can a sophisticated person in a modern metropolis function happily in a relationship, sustain an emotional connection or even recognise love? Via the uncertain romantic Robert, Sondheim windows into the lives of five married couples and three women to explore these ideas in all their hilarity and complexity.
