Jon Bon Jovi ended Thursday’s Madison Square Garden concert after about 90 minutes because of a sinus infection, with his spokesperson now confirming the illness as the cause. He apologised to the audience and said ticket holders should keep their stubs while arrangements for a rescheduled show are worked out, affecting a prominent date in the band’s return to touring.

Bon Jovi told fans he felt well but needed to stop for the evening, then hugged his bandmates before leaving the stage. The concert is part of the Forever tour, which began earlier this month following a four-year touring break after the singer underwent surgery for a strained vocal cord; he said in June that he was fully recovered.
