Hmmm, yes. I think applause at funerals is a traditional Continental European thing, and that it was Lady Diane's funeral that it all became "the thing to do" in the UK in order to celebrate life rather than show sympathy for passing.
I can see a point although if someone I know dies I think I'd prefer to be silent than applaud, as a former serviceman I think silence in commemoration is appropriate.
When I go I want a mariachi band, dancing girls and a Polar Bear fighting an Ostrich as half time entertainment before Arthur Brown lights the blue touch paper on my funereal Air Bomb.
