If family leaves the memorial meeting to the organization they will get the stale organizational pitch.
My personal experience is that if family wants the service to be personal, the family has to request it. One of the best ways to do that is to select who the speaker will be. Then spend a few minutes with the speaker to let him know that you want it to be personal.
It can be done.
Glad it worked out well in your case, min. Sorry to learn of the loss of your brother.
