To not want DH to do a reading at his friend's funeral?

[fingersandwich]

My DH's friend tragically died last week in an accident. He was only 35. His funeral's on Monday and my DH is doing a reading. He's written some stuff that I don't think is appropriate for the situation, especially as his kids will be there. It's a bit sweary and references activities that are not strictly legal. I've no idea why he thinks this would be OK to read out. His friend's widow wants him to read a passage from her husband's favourite book, which is much more sensible. How the hell can I convince him that this would be a much better idea?!

I'd ask him to respect the wishes of the widow here. I know he's probably seeing it as 'he was my friend so I have a right to say what I want' but as PPs have suggested, there are more appropriate venues for his speech. At the funeral I would put the woman who is burying her 35 year old husband first.
