Dozens of fans are camped out in Peru's capital in hopes of being the first to enter Monumental stadium for Monday's concert by former Beatle Paul McCartney.

Ticket-holders began lining up at the stadium's entrances on Thursday and some of them brought tents to make the vigil more comfortable.

The aim of the early birds is to get the best vantage point to view the performance by the 68-year-old McCartney, whose stay in Lima will include receiving a medal from the Peruvian government for his environmental activism.

More than 30 members of McCartney's road crew arrived here 10 days ago to begin preparations for the concert, media outlets said.

In a bow to the musician's vegetarianism, the stadium's food concessions will offer three Peruvian-potato dishes created especially for the concert.

Tickets for the much anticipated performance are selling for between 260 and 1,975 soles ($100-$745) and the promoters issued a warning Friday about counterfeit tickets that are being touted on Facebook.
