A funeral need not be a ‘vulgar show’, BigLouis. My mother’s was very simple, with the music and hymns she liked, inc. a beautiful recording of Panis Angelicus, soprano solo by a Gdd with her school choir.
I’m not at all religious, but I found it both fitting and comforting. Since my Dm was 97 there weren’t many attendees - we had drinks and a simple lunch in our garden afterwards.
Not long ago, sitting outside a SW London pub, I saw a horse drawn hearse go by - black horses with plumes on their heads, top-hatted undertakers in black + it was like something out of Dickens - quite a spectacle.
And IMO if that’s what the family want, that’s their choice.
