Coldplay to go back to the future at Super Bowl show
Coldplay singer Chris Martin says the band's Super Bowl half-time show will try to honour the past, present and future.
At a news conference, the band's members said they will have the Youth Orchestra of Los Angeles there to represent the future and Beyonce - whose 2013 performance they adore - for the past.
"We've watched all of the other half-time shows many times, and most of them are fantastic," Martin said.
"I think we're going to try to celebrate those other years and hopefully make a show as memorable as some of our favourites."
Coldplay, whose well-known songs include Yellow, Speed Of Sound, Viva La Vida and Magic, declined to speak about the other performers set to the hit the stage on Sunday at Levi's Stadium in Santa Clara, California.
When a reporter asked Martin if his children, Apple and Moses, would watch, he said: "I hope they'll watch. What else is on that day?"
He added that his son designed two pairs of shoes for him - one he wore at the news conference and the other for Sunday's big performance.
Though Beyonce is performing on Sunday, the band said they would not play their new collaboration with the diva called Hymn For The Weekend, which they recorded for their latest album, explaining that it only recently came out.
"I don't think it would be quite right," Martin said.
But he stressed they are big Beyonce fans: "We love Beyonce's music. She's one of our all-time favourites, and she's one of the greatest performers I've ever witnessed."
The band, which includes Jonny Buckland, Guy Berryman and Will Champion, said they spoke at length with one another about what their performance should represent.
"We decided we wanted to make it about togetherness, acceptance and the things we believed in. Then we called the right guests, so we know that we have great people joining us," Martin said.
Asked how they would fit 16 years of music into just 12 minutes, the frontman joked: "We decided we'd play all our No 1s, and then work out how to fill the other 10 minutes."
The Carolina Panthers will face the Denver Broncos at Super Bowl 50, but Coldplay would not be drawn into revealing who they will support.
"I think we're firmly split down the middle between those of us who know absolutely nothing about football and those of us who know almost absolutely nothing about football," Buckland said.
