What did Frédéric Chopin blue plaque do at 4 St James's Place?

The Story

Looking up at this elegant townhouse in St James's Place, it's poignant to imagine a frail Chopin spending his final months in London here in 1848, where he found brief refuge during France's political upheaval. Though gravely ill with tuberculosis, the composer rallied enough strength to give what would be his last ever public concert, departing from this very doorstep to perform at London's Guildhall on November 16th. Despite his weakened state, he played his beloved works including nocturnes and waltzes for an audience of 1,500 people - a remarkable final flourish before returning to Paris, where he would die less than a year later.
