Here's who I've decided to go with!
Circus Performers: Tatiana Valentino- Tati, Linnea Hawethorne-TheLittleSinner
Roadie/Tech: Nicholas Carter - FrankieXIero
Fangirl: Gabriella Sage-Marie Rae-xxPanicFanxx
Groupie: Analeigh Blackburn- gunpowderandlead

Thanks again! Now, I'm also looking to cast ONE MORE groupie. So, midnight_star22 or kaelamonsterdino, if you'd be willing to let me use your characters for that role please let me know!
Thanks a million! Once again, the story will be titled "The Boy with The Voice"!
