If IRC, that song is actually one of the most recognizable songs around the world....everyone knows about the claps!
What song is that? I grew up two states away from Texas, and worked in Dallas for some time, and the only thing I can come up with is Chuck Norris's "Eyes of a Ranger". I'm pretty sure that's not what you mean.
See the other comments below. Deep in the Heart of Texas. Once you hear it though, you'll instantly recognize it. YouTube it.
Yeah, but non-Texans didn't standup in front of their school in 4th grade with a cowboy hat and red bandana and sing the shit out of that song. We practiced for weeks.
