This would make me less sad about the rest of the article.

 So I got a News notification  *Casting Spoilers for Hotel Babylon main cast in article* in my email today about Hotel Babylon and it lists John Barrowman as a guest star for the upcoming season.  Has anyone heard anything about this?  

I'd love to see him guesting in other shows as time permits.  It's nice to see some other sides to his acting other than Captain Jack.
