FORT WORTH — By the sounds of it, you'd think it was the start of a concert.

But what you can see in multiple YouTube videos posted online was actually a pep rally for the state STAAR test at Morningside Middle School in Fort Worth. The man seen in the videos hyping up the kids is a local rapper named Go Yayo. The music video for his song "Boom God," also available online, shows guns and violence.

"I'm still in awe," said Charleston White. "I'm still in shock we would take this to our children."

White, along with Jesse Taylor, run a local mentoring non-profit group called "Hyped About HYPE." They are amongst those criticizing Fort Worth ISD. They question why the school would bring Go Yayo to speak to middle school children.

"I got shot when I was 15; my cousin got murdered all over this rap stuff," says Go Yayo in video recorded at the pep rally.

"Very distasteful," White said. "Extremely distasteful, and someone should be held accountable."

District spokesman Clint Bond says the school's principal didn't know Go Yayo would be part of the May 6 rally.

"She didn't approve that person coming," he says.

Bond says the principal claims a local radio station brought him. The radio station's manager says absolutely not, that the rapper's appearance had nothing to do with them. He adds they brought their own entertainer with them, an R&B artist.

"There was some sort of miscommunication," Bond says. "I don't know what it is, but I can probably tell you it won't happen again."

Late Wednesday afternoon, after backing out of an interview, News 8 received a statement from Go Yayo's manager clarifying who invited the rapper to perform -- no one:

Kyrin "Go Yayo" Peters grew up in Fort Worth and went to school in the FWISD school system. He has a profound love and admiration for the youth who look up to him. He was not invited by FWISD nor 97.9 the Beat to participate in the pep rally at Morningside Middle School. After hearing about the radio station going to the school he took it upon himself to join the event in hopes to encourage and motivate the students. His intention was not to promote violence or bring negativity to any parties involved. This was simply a young man trying to utilize his influence to give back to the community that he grew up in by encouraging kids to not follow his footsteps but to stay in school and be excited about school. We send deepest apologies to any students, parents, or faculty that may have been offended by his attendance.

Even though Go Yayo's speech did focus at times on encouraging the kids, White and Taylor worry about what kids will see when they go home and Google him.
