A Posh Single?

Apparently, Tom and his Posh co-stars Harry Hadden-Paton and Henry Lloyd-Hughes were in the studio today recording...something!  Harry (@haddockpate) was kind enough to post a link to a photo.  He called what they were recording a "single" -  it'll be interesting to see what it is used for.  He also tweeted that there would be rehearsal photos taken today and perhaps some interviews, so it sounds like the Posh PR machine is certainly gearing up for the opening of previews - 2 weeks from today!
