This street festival, one of the best in the West End, runs from 4pm to 6.30pm, while the Conran Shop special promotion continues until 8pm.
Father Christmas has his own grotto at the entrance to Beaumont Mews, stylishly decorated by Cath Kidston, with free wrapped gifts for children. Light-spinners will also be handed out for free, with collections for children’s medical charity Sparks.
The Royal Academy Brass Band Quartet will perform and children from local schools will sing carols. The main focus of events will be a stage at the intersection with Devonshire Street (the streets will be closed to traffic).
The lights go on at 6pm, with fireworks, snow, and music by Hear Me Now! from the BBC series Last Choir Standing. And look out for special guest Gabby Logan, the sports presenter who gamely took part in Strictly Come Dancing.
Enjoy hot food and drink at points all along the street, including mince pies, hot chocolate, mulled wine and barbecued food.
Cabbages and Frocks will host a street market. For more details, go to www.marylebonechristmaslights.com.
