Paul McCartney rumored to headline Firefly

On the debut Beatles album "Please, Please Me," George Harrison sings, "Do you want to know a secret? Do you promise not to tell?"

Well, nearly 52 years later in the age of social media and smartphone, keeping secrets is harder than ever.

And if the rumors swirling around the 2015 Firefly Music Festival lineup are true, Paul McCartney will headline the 80,000-person rock fest in Dover June 18-21.

It would be his first time performing in The First State.

The other two headliners are reportedly Kings of Leon and Las Vegas rockers The Killers, who were a headliner at Firefly's inaugural bash in 2012.

So where are these rumors coming from and are they legit?

It's hard to be certain, but they originated on the fan-run Bonnaroo message board Inforoo by a user that posts under the name "infinitypass."

According to AlternativeNation.net, the user is a "well known Inforoo insider who has been 100% accurate in festival leaks over the years. The same source has called the Bonnaroo and [New York's Governors Ball Music Festival] headliners for this year before they dropped."

McCartney, 72, currently has no future concerts listed on his tour schedule.

Lauren King, a spokeswoman for Firefly, does not confirm or deny the rumors.

"The official lineup announce is coming soon and we're excited to share with fans," she says. Previously, King said fans should expect a lineup announcement in early February.

McCartney headlined the Coachella Valley Music and Arts Festival in 2009 -- a festival founded by AEG's Goldenvoice, which is now a partner with Firefly organizers Red Frog Events.

While The Beatles never performed in Delaware, the band was once in the state while on tour, says Wilmington's Joel Glazier, a Beatles expert who gives speeches for the Delaware Humanities Forum about the band at colleges, schools and civic groups.

After The Beatles performed live on "The Ed Sullivan Show" in New York Feb. 9, 1964, the Fab Four were due for a show two days later at the old Washington Coliseum in Washington, D.C.

However, a blizzard forced the band to abandon their planned flight and charter a train car -- one that passed through Delaware. They returned to New York the next day on another train for a show at Carnegie Hall.

"So all four Beatles were in Delaware together – twice. Every state cannot say that," Glazier says.

As for the news that McCartney might actually perform in Delaware 51 years later has this Beatles fan singing, "Yeah, yeah, yeah!"

"What a small wonder this state is to get the world's most successful performer in rock music to perform here among the mosquitoes, heat and humidity," says Glazier, who had given up on McCartney ever performing in Delaware. "I'm trying to stay calm."

McCartney wouldn't be the first Beatle to perform in Delaware, however.

Ringo Starr played the Bob Carpenter Center in Newark in 1997 and Beatles drummer Pete Best, who Starr replaced, has performed multiple times at Kelly's Logan House in Wilmington over the years.

Glazier jokes, "Paul is finally catching up with Ringo."

In other Firefly news, the 2015 map of the festival grounds was released Thursday. The Arcade is now The Beercade, so fans can expect an arcade with a bar selling a variety of beers, organizers say.

The festival also launched a new video re-capping the 2014 festival and a new blog, The Record, with its first post published Thursday by festival director Greg Bostrom.

Bostrom gave fans some insight into how Firefly picks its acts and closed by saying this about the 2015 lineup: "We can't wait to reveal it to you in a couple of weeks."
