Soccer fans and bad behavior go together like peanut butter and jelly, which makes this so surprising.

A group of Irish soccer fans in France for Euro 2016 were on a train when they belted out "Twinkle, Twinkle Little Star" to a baby who was riding the rail with her parents. The group followed that up with a raucous version of "Hush, Little Baby."

The video, which is a terrific mixture of fun and sweet, has gone viral. When you mention the word "pitch" in soccer, you automatically think the field of play, but these guys make you think "pitch" in terms of carrying a tune.

Yes, soccer fans are often associated with acting like louses, but this was certainly a nice gesture.
