Today’s funeral as been dubbed the “funeral of all funeral” with rumours swirling £100,000 is being spent on a huge bash.
It came amid high tension in Hither Green, where friends and family members of Vincent had staged pitched battles with locals over floral tributes last month.
Vincent's coffin was carried in a silver hearse vehicle, with a floral display spelling out the word "Daddy" alongside it.
It was followed by several other cars with flowers on their roof.
The convoy passed the church and continued up the road to park.

LBC’s Mike Hughes said he had had bottles thrown at his face.
He said on air: “Chaos has descended here. In my 10 years as a journalist, I have never felt so under threat.
“I’ve had bottles thrown in my face. I am covered in egg, which was pelted at me.
“It all came from members of the funeral cortege. I was surrounded by people who were very angry, very upset and became very violent, very quickly.”
