Post-shrimping incident. Many sailors died that day. James once told me the horrors of the sea from that fateful day. Nets upon nets were being filled with the largest most succulent shrimp a man could ever eat. "The emperors of Rome would be envious!" he told me. The ships cargo holds were nearly filled when a quiet came upon the ship and her crew. A warrior-esque shrimp creature came out from the warm Caribbean waters, donned in armor and wielding a spear. The spear, James said, looked as though it had killed a thousand sailors in it's past if it's killed one. The crew went to arms and attacked the shrimp, and one by one they were slaughtered. After several minutes, it was down to James and the Shrimp creature. James realized there was only one way to kill the mighty beast. He would have to expose himself to attack to get the Shrimp's weak point. He grabbed a spear and charged the Shrimp. The Shrimp lowered it's spear and charged at James. James sprung into the air with a horrifying war cry. The Shrimp let off the most disgusting sound ever heard by man.
WhOOSH, WHOOSH.
The Shrimp collapsed on the ship's deck in the blood of James fallen comrades. Slain, the Shrimp was. Our hero, however, had taken the Shrimp's mighty weapon to the throat, where his vocal cords were injured. He clenched his throat and quickly found bandaging. Once the bleeding stopped and he regained some strength, James gave all a burial at sea - that damned Shrimp included.
To this day, no one knows if there are more warrior Shrimp in the sea. James was promoted to Captain after the fierce battle. He continues to sing for his band, Dream Theater. Fearful that his Earth defying F#'s may have caused the creation of the Shrimp (it's science, look it up if this doesn't make sense), he only hits the note on occasion. Knowing, fearing, that another Shrimp would be born.
edit: In all seriousness, I think James is the better vocalist. I'm actually happy that the food poisoning incident happened. His voice has matured and, I think, has added so much to Dream Theater's music.
