As Xmas approaches, some shops and areas will make an effort to decorate their world.
The shop windows of the larger stores like Selfridge’s were famous for their displays. Lights go up on Oxford Street, Regent Street. The Strand and many other places too. Mostly they are adverts for films, tv channels or shops.
Covent Garden still has a tree. You may be lucky and catch a carol concert there one evening. Do donate, for charity.
