Pop Goes The News — Legendary crooner Tony Bennett appeared confused Thursday night before abruptly ending his concert in Montreal.

The 89-year-old acknowledged “Toronto” and performed only five or six songs before he walked off the stage, according to audience members — including some who had paid more than $200 for tickets.

Bennett was the first headliner at the newly re-opened Cabaret inside the Casino de Montreal.

“Unfortunately, Mr. Bennett was forced to end his performance due to issues affecting his voice,” read a statement from the Casino on Friday afternoon.

According to reports, the singer declared that he was delighted to “open” the casino — which, in fact, opened in 1993 — and he thanked “Toronto” — where he last performed in April.

Montreal mayor Denis Coderre was among those at the show.

One fan reported that after performing “Make Someone Happy,” Bennett started singing the song again — only to be told by his bandleader that they had just done the song. Bennett then performed “I Left My Heart in San Francisco” before saying “good night” and leaving the stage.

Tickets for Bennett’s concert, which was scheduled to last just under 90 minutes, were priced from $218.55.

The Casino de Montreal said “the reasons that lead to the interruption of Mr. Bennett’s performance went beyond the control of the Casino” but it will give ticket holders a 50 per cent refund and a ticket for another show.

Bennett is scheduled to perform Saturday night in Cincinnati.

His next Canadian dates are Oct. 15 and 16 at the Avalon Ballroom Theatre at Fallsview Casino Resort in Niagara Falls. Tickets were priced from $70.
