Cuckooed, Traverse Theatre *****
Mark Thomas's new show is in the theatre section of the Fringe brochure, but this hour, full of laughs and witty lines as it is, could easily be under the heading of comedy. Indeed, Thomas once made his living as a stand-up, even if his career has long defied any pigeonholing; professional irritant, activist and satirist are just a few job titles that could apply.
