El Mundo newspaper and other media outlets said Thursday that tickets for the band's sold-out concert June 27 cost between 18 euros ($23) and 39 euros, roughly half normal prices for such concerts.
The paper's website quoted the singer as saying they initially planned not to play Spain, fearing poor demand from cash-strapped fans.
But he told El Mundo, "I didn't want to let fans down" in a country he loved. So the band decided to drop their performance fee, meaning the ticket money will only cover the other costs of staging the concert.
