The Rolling Stones, currently still on that US tour, have a defibrillator backstage in case anyone collapses from a heart attack, or they do according to The Sun. A source apparently said: "With all four band members now veterans, their managers are not taking any chances."
Not sure I buy it. It would seem not a little pessimistic and hardly very rock and roll. A spokesman for the band said: "I've never seen a defibrillator backstage". And I, for one, believe him.
