You can’t keep a good man Down(e); and after a five year absence from the Edinburgh Fringe, cabaret’s most glorious toupeed lounge singer is back, spreading an infectious grin over a captivated audience that is as wide as the act is broad.

Yet, inbetween the knowing winks to audience that suggest he’s in on the joke as much as we are, there’s also real character subtlety and individuality here, and terrific musicianship, too - not to mention, of course, the silliest dancing this side of Pan’s People and Hot Gossip.

He’s also come home to possibly the best place in the world to see him, namely the intimate confines of the splendid Spiegeltent, the most gorgeous of any travelling fringe venue that in its mirrored, wooden circular embrace feels like a throwback to another age.

So, too, naturally is Bob - in his two-piece “safari” suit and gleaming teeth (people, he says, think “the hair is real and the teeth fake”), he’s a dazzling emblem of 70s wholesomeness; and his pop repertoire reflects it, too, with songs like ‘King of the Road’, ‘Music to Watch the Girls Go By’ and ‘You are the sunshine of my life’.

He’s joined on this outing, so to speak, by sometime girlfriend Pastel Vespa and family member Glen Twenty.
