I appreciate your comments but surely Gingernuts as , I assume , a neighbour to the gardens is entitled to his views as well. His garden may very well back onto the Gardens as he is trying to read a book in his garden when there are many thousands over the fence chasing chicken , some worse for drink.
I wonder how good old Mr Horniman would think , after all he donated the house and land for the museum and gardens ( the word is gardens not park ).
Not sure he would expect such occasions as the infamous poultry evening.
Would not Dulwich Park be more suitable for such events and leave Horniman's for more sedate occasions.

But what do I know.
