Santana, Sting, Ricky Martin and Esperanza Spalding will play the 45th Montreux Jazz Festival, organisers have announced, after the programme was leaked online.

Festival organisers had planned to announce the line-up on April 14, but moved the announcement forward after discovering it had been leaked onto the internet on Tuesday and soon afterwards in Swiss media.

"There were leaks, but I can't confirm we were hacked," spokesman Pascal Buchs told Reuters.

Carlos Santana and John McLaughlin open on Friday, July 1 in the Stravinski Auditorium and return to the stage two nights later along with Susan Tedeschi and others in a tribute to blues king B.B. King, who plays his own gig on July 2.

Deep Purple will perform with a symphony orchestra. Other big names include Ricky Martin, Sting and his “Symphonicity” tour, George Benson, Diana Krall, Dr. John, Seal and Paul Simon.

Quincy Jones will lead a collaborative tribute to Miles Davis featuring Marcus Miller, Herbie Hancock and Wayne Shorter.

Other artists include: Esperanza Spalding, Afrika Bambaataa, Arcade Fire, Raphael Saadiq, Jimmy Cliff, Femi Kuti and Liza Minnelli.
