Peter. Bjorn and John at final day of Coachella

 The bongos came out during Peter, Bjorn and John's set and that could only mean one thing, they were getting ready to play "Young Folks" or the "whistle song," as described by a fan at the third day of Coachella.

Besides bringing out the instruments, the trio also brought out some guests for a couple of their songs during their set.

The band, which is best known for their single "Young Folk," brought out fellow Swedish singer Lykke Li for the performance. Just prior to that they had brought out Robyn for their latest single "Nothing to Worry About."

The group was making the leap from a tent performer in 2007 to the main stage where they were on Sunday.

"We played two years ago but this better," Peter said. He was talking about how Paul McCartney had played that very stage just two days before.

They played several songs from their new album "Living Thing," opening up their set with "Just the Past."

But almost immediately into their set, the crowd was thrown off with the sound. The bass was so high your body vibrated.

That prompted a fan nearby to say that's "a little more bass than I need."

But the fans didn't seem to faze by it and just continued singing along with Peter.

As the indie band got into their second song, "It don't move me," a group of fans moved their way through the crowd waving a Swedish flag.

From "Lay it down" to "It beats me," off their 2005 album Falling Out, they seemed to be having fun.  I enjoyed watching Peter, who was either dancing in place or bopping around. At one point Peter went down the stage and danced with the fans.

But the inevitable occurred during their set, a "fan" asked who was who?

It's almost as if Peter had heard her, or they must get that question a lot because he introduced himself and his bandmates.

"This is Peter," he said of himself, "this is Bjorn and this John."
