Mick Jagger‘s health is in such a highly uncertain, precarious or threatened condition that his doctors, out of the blue, have told him he can’t perform in the next phase of the Rolling Stones’ “No Filter” tour, which would’ve launched only three weeks from now in Miami. Or at least not until Mick receives “medical treatment.”

And so the tour has been deep-sixed until further notice.

An official statement, quoted by Variety, says that “doctors have advised Mick that he is expected to make a complete recovery so that he can get back on stage as soon as possible.”

Medical prudence is always a good idea, but in terms of the enormous physical and financial demands of a major Rolling Stones tour, cancelling only three weeks before kickoff suggests a certain urgency. One presumes that Jagger’s unspecified health concern is outside the realm of the usual transitional ailments.

Arguably the the leanest, spry-est and healthiest-seeming 20th Century rocker around, at least as far as appearances have been concerned over the last half-century and beyond, Jagger is 75 and 2/3. He’ll hit the big seven-six on 7.26.19.

Jagger statement: “I hate letting our [North American] fans down and I’m hugely disappointed to have to postpone the tour but am looking forward to getting back on stage as soon as I can.”
