Info from Licensor: "Our Two year old twins woke up at home on the morning of the Eagles game and began singing the Eagles fight song to each other. The twins, along with their 5 year old big sister have grown up Eagles fans as their parents are season ticket holders and always chant the song to them on game day. However, this is the first time the twins have sang the song unprompted on their own!"
