Quoting from the Unity Day web site -

Hyde Park Unity Day is a day of celebration for the local community to
show the best of whom we are.

The community had lost a local Pub, the
'Newlands' through riots in 1995, which attracted intense national
media coverage and this led to a negative portrayal of the area which
we as a community had to come to terms with ourselves. Hyde Park Unity
Day is an association of individuals who give their time and talents
freely to create a day celebrating our area and our diversity.

We have
a Management Committee to help us stay on course with budgeting and
planning and Area Co-ordinators who organise the various tasks that
have to be done to ensure a day everyone can enjoy. Every year there is
a core of people that have been involved in previous years, but we are
always on the look out for new talent.
