Yes the Blues Bro's are going on tour or Aykroyd and Belushi are.

In a recent interveiw on Conan O'Brian thats would Belushi said

Blues Bros. on tour? Don't know if that would be as good, considering John Belushi's dead. As for the cast:
Ernie still gets bit parts in some movies, such as Miss Congeniality.
Dan does great cameos and bit parts, as he played in Pearl Harbor as Thurman (I was surprised to see him in the movie!).
Bill's still trying to save his career, I suppose. After the failure Osmosis Jones, he's in desperate need for a good hit.
As for Harold, I honestly don't know what's up. He may be directing still, or, better yet, writing a screenplay (I hope!).
Annie's still doing new episodes of Any Day Now for Lifetime.
Sigourney's latest movie, Heartbrakers, was just released on video and DVD, and that's all I know about her lately.

The best place to go to check out what the cast are doing is The Internet Movie Database: www.imdb.com I love that Site!

More on Bill:
I just saw the trailer for his latest movie! It also stars Gene Hackman, Danny Glover, and a few other good actors. I believe the title is The Royal Tannenbaums, and it looks to be pretty good.

The Royal Tennenbaums! That's the name! Good job, Turtle!
I heard about it and it looked to be good. I believe it was made by the maker of Rushmore, and I liked Rushmore, personally, so hopefully this movie's good, too.
