Cage the Elephant took to the stage on Friday at the Firefly Music Festival, and you would have thought the crowd was waiting for years to see them. Fans filled every bit of space at the Firefly Main Stage early in the evening and loved every single second of the hour-long set.

The energy was absolutely off the charts from both the crowd and the band on stage. At one point, frontman Matt Schultz ran from the back of the stage and jumped into the crowd. He took his microphone – cord and all – with him, and kept on singing.

There was no downtime during the set, and Cage the Elephant even paid tribute to former Beatle, Paul McCartney, who would take the same stage later in the night. Fans cheered and then joined together to sing "Happy Birthday" to McCartney, who had turned 73-years-old the night before.
