Ah, this morning's lavish coverage of Mick Jagger turning up at Dave and/or Boris' expensive Davos tea party must have thrilled the Number 10 press office.
The grins have probably faded somewhat, as Jagger has pulled out, fuming at being described, for example, as a Tory by Gordon Smart this morning:
The Rolling Stones frontman said: "During my career I have always eschewed party politics and came to Davos as a guest, as I thought it would be stimulating.That's pretty much a disendorsement of Cameron, then. Or possibly of Boris. Or probably both.
"I have always been interested in economics and world events.
"I now find myself being used as a political football and there has been a lot of comment about my political allegiances which are inaccurate.
"I think it's best I decline the invitation to the key event and curtail my visit."
