This takes place annually on Maundy Thursday and is generally at Baldwin's Omega just off the top of Psalter Lane. The most recent one (2006) attracted some 170-odd OEs representing the eras of Graham (ie 1930s) onwards. There were at least 15 from the Barton years, and many more from the Clapton years.
