What song is played when patriots come on the field?

they play the eagles fight song...Fly Eagles Fly ...and it goes like this... "Fly Eagles fly, on the road to victory, Fight Eagles fight, get a touchdown one, two three TWO THREE!!! Hit 'em low, hit 'em high, and watch our Eagles fly So fly Eagles fly, on the road to victory! E-A-G-L-E-S EAGLES!!!!!!!!" (brings a tear to my eyes every time I hear/sing it!) GO EAGLES!!!!!!!!!!!!!!!!!!!!!!!!!!
