The Eagles might go 17-0 this season ... and it's all thanks to Coldplay's beautiful performance of the team's "Fly Eagles Fly" fight song at their concert in Philadelphia.
The show went down at Lincoln Financial Field -- home of the Eagles -- on Wednesday ... as part of the band's "Music of the Spheres" tour.
The group made sure to give the hometown fans what they REALLY wanted ... pausing their regularly scheduled setlist to bring a tear to any Eagles fan's eye.
Of course, the tune is usually shouted out by any drunk fan wearing a Brian Dawkins jersey at the bar on NFL Sundays .
