Coldplay knows how to play to the hometown fans.
At Wednesday's show at Lincoln Financial Field, lead singer Chris Martin busted out a rendition of the Eagles fight song "Fly, Eagles Fly".
As you might expect, the crowd lost their minds - and joined Martin in chanting "E-A-G-L-E-S EAGLES!"
I think people also would have lost their minds if he broke out into "Here They Come", the 76ers super popular song played when the team wins a game at home.
What are some of your favorite sports-related chants and fight songs?
