Classic football song, sung by many, this one by K.V. Kortrijk (Ed: Not the full song but worth putting up)
Lyrics
On when the reds go marching in, Oh when the reds go marching in, I wanna be in that number, Oh when the reds go marching in... On when the reds x2 Go marching in x2 On when the reds go marching in. I wanna be in that number, On when the reds go marching in...
