• The 69th annual Clowns’ Service will be held this Sunday – but the venue has changed. An annual tradition since 1946, the service is held in memory of Regency performer (and man hailed as the “inventor” of the modern clown), Joseph Grimaldi (1778-1837). It has been held at Holy Trinity Church in Dalston since 1959 after the previous building where it was held – St James’ Chapel in Pentonville Road; site of Grimaldi’s grave – was gutted in a fire (permission was given for clowns to attend in costume in 1967) but this year, due to repairs at Holy Trinity, the service is being held at sister church All Saints, Livermore Road, in Haggerston (E8 4EZ) (www.trinitysaintsunited.com). Kicks off at 3pm but you’ll have to be early to find a space. About 60 clowns usually attend and a clown show for children follows.

• Bronze sculptures and drawings of babies and children by Sir Jacob Epstein (1880-1959) form the basis of a new exhibition opening tomorrow at the Foundling Museum in Bloomsbury. Sir Jacob Epstein: Babies and Bloomsbury features portraits of Epstein’s own children and grandchildren and those of friends and contemporaries. The artist lived in Bloomsbury himself between 1914 and 1927 during which time he had five children from a series of extramarital affairs (interesting his long-suffering wife Margaret, herself unable to have children, brought up the youngest and oldest of these and put up with his affairs until her death in 1947 – although she is believed to have shot his long-term lover Kathleen Garman, later his wife and Lady Epstein, in the shoulder with a pearl-handled pistol. Also opening at the Foundling Museum tomorrow is a display of four rarely-exhibited portraits of Georg Frideric Handel and contemporaries Corelli, Geminiani and Daniel Purcell which are on-loan from the Royal Society of Musicians and which once hung in the royal box of King George III. Both exhibitions run until 10th May. Admission charges apply. For more, see www.foundlingmuseum.org.uk.
