“The proposals on the table are hopeless. Either the museum is to stay in its current premises until its 22-year lease expires, bolstered by some undefined partnership with neighbours such as the Royal Opera House. Or the Covent Garden premises will be vacated, and exhibition space for the collection shoe-horned into the V&A’s South Kensington site. Such blinkered thinking has dogged the Theatre Museum ever since it was first mooted in the 1950s.”
