2ND UPDATE: Jay Leno, David Letterman, and Jimmy Fallon are in repeats tonight. But Conan O’Brien‘s show is original and Boston is his hometown so he comments on today’s bombings (below). So does Jimmy Kimmel (below). Also Craig Ferguson (video below) who notes during his cold open that, when he became an American citizen in 2008, he spoke at Faneuil Hall on July 4th at the invitation of Boston Mayor Tommy Menino:

CONAN O’BRIEN: We have a great show for you tonight.  But first, I have to mention what an upsetting and sad day it’s been. Boston is my hometown – it’s where I grew up, and it’s where my family lives.  So I just wanted to take a moment to say that – like everyone here – my thoughts and prayers are with the people of Boston and everyone who has been affected by this senseless act.  That said — it is our job to do a show. We’re going to try and entertain you the best we can. Which,  given our track record, gives you people a 20% chance of having a good time tonight.

JIMMY KIMMEL: Well – it was a terrible day. Very bad things happened today for no good reason – and our thoughts are with the people of Boston and everyone who is suffering as a result of the bombings at the marathon. It’s a disgusting thing. I don’t understand it. But my job is to make you laugh and so I will try to do that. And – I will probably fail. I’m failing already.

Folks, it could be "ironic". The fact that his/her 3 favorite hosts happened to actually be filming...

CRAIG FERGUSON: Hey everybody, good evening. Tonight’s show is a little bit different. Obviously the news of today is so horrendous that it would seem insensitive at best to say ‘It’s a great day for America,’ so I won’t be starting the show with that tonight. Is anyone else sick of this sh**? I seem to have to say that too often.

People say to me ‘Craig, your job is to make people laugh at the end of the day.’ And I think, yes, that’s true, but I’ve never professed to be any damn good at that. And, the thing is, people want their mind taken off it. And I think, well ok, if you want your mind taken off it, you know, watch a cartoon or a video or something. I understand it, it’s perfectly acceptable. I don’t think it’s a terrible thing to not want to think about it, but I can’t not think about it.

Also, I have a personal connection with the city of Boston. I have some history there. I have family there. When I became an American citizen in 2008, I spoke at Faneuil Hall on July 4, at the invitation of Tommy Menino who is the mayor of Boston, and one of the more colorful characters in American politics…. I’ve been there for the Fourth of July many times… and every cop in Boston looks like I’m his brother… My first stand up special in America, I shot it in Boston. I like that town . I’m appalled by this thing and when I watch it on these streets that I know, it’s horrifying.

If I have all this inside of me. If I have all this rage and anger and distress and upset inside of me, I’m not a good enough comedian to hide all that from you.
