• Almost 50 buses, from a horse-drawn model of the 1820s to the New Routemasters of today, will come to Regent Street on Sunday in celebration of the Year of the Bus. The ‘Regent Street Bus Cavalcade’ – which will stretch from Piccadilly Circus to Oxford Circus and will see the iconic West End street closed to traffic – will also feature a variety of free family events including Lego workshops (there will be a bus shelter and bus stop made entirely out of Lego outside Hamley’s toy shop), children’s theatre performances, a pop-up London Transport canteen and the chance to have a personal message recorded by the voice of London’s buses, Emma Hignett. There will also be an exhibition – Battle Bus – which provides information about the B-type bus (a newly restored version of which will be on display) which was used during World War I to carry soldiers to the frontline as well as ambulances and mobile pigeon lofts while jewellery company Tatty Devine will feature a special range of bus-inspired jewellery and hold jewellery-making workshops on board a London bus. The cavalcade, supported by the Regent Street Association and The Crown Estate, is part of Transport for London’s celebrations marking the Year of the Bus, organised in partnership with the London Transport Museum and the capital’s bus operators. The free event runs from 11.30am to 6pm. For more information, see www.tfl.gov.uk/yearofthebus and www.ltmuseum.co.uk.

• A new exhibition of materials showing how people coped at home and on the front during World War I opens at the British Library in King’s Cross today as part of efforts to mark the war’s centenary. Enduring War: Grief, Grit and Humour features personal objects such as letters, a handkerchief bearing the lyrics of It’s A Long, Long Way to Tipperary, Christmas cards, school essays about airship raids over London sit and recruitment posters, humorous magazines and even a knitting pattern for balaclavas. Highlights include a letter in which Sir Arthur Conan Doyle expresses his concern over his son serving at the front, manuscripts by war poets such as Rupert Brooke as well as Wilfred Owen’s manuscript for Anthem for Doomed Youth, Vaughan Williams’ A Pastoral Symphony and Laurence Binyon’s For the Fallen. A specially commissioned video and ‘soundscape’, Writing Home, features personal messages contained on postcards written to and from the front. A range of events accompanies the free exhibition. Runs until 12th October. For more on the exhibition, see www.bl.uk.

• Nominations have reopened for English Heritage’s Blue Plaques scheme in London. In 2012 nominations were temporarily suspended while new funding for the scheme was found and thanks to one individual’s donation and the creation of a new Blue Plaques Club to support the scheme on an ongoing basis, they have now reopened. There are 880 official Blue Plaques on London’s streets – remembering everyone from Florence Nightingale to Fred Perry and Charles Darwin. For more and details on nominations, see www.english-heritage.org.uk/discover/blue-plaques/.
