(((((Rhap)))))) That might be a nice idea if you think everyone could handle it. I have a VHS of my dad's retirement party (he was a bigshot at an airline, people came from literally all over the world to wish him well) and I haven't ever been able to watch it because I think it would just be too hard on me. He'll be gone 10 years in August.
I hope you and your family can find comfort in the many good memories I'm sure you have.
