Why bother going to see West End musicals when you can see snippets of the best of them at Harrods? Starting next month, the luxury department store will be hosting a series of mini performances from West End shows including Mamma Mia, Chicago and Avenue Q. There will also be performers from the English National Ballet and television show Strictly Come Dancing. According to Harrods officials the idea is to “entertain shoppers amid the doom and gloom on the high street”.
