Seen, but not really heard: Walnut Creek native go-to trombonist for hit series ‘Glee’

"There are no rehearsals," said Hughes. "The cast members are all very, very professional. They come out ready to go, knowing their songs and dance routines. They don’t mess up. But they have to do everything over and over again so the camera crew can get every camera angle."

The script for the “West Side Story” audition of Kurt Hummel, played by Chris Colfer, called for him to climb a scaffolding on stage, swing himself around on it and then twirl swords all while singing, “I Am the Greatest Star,” from “Funny Girl.”

"Chris had to do that number over and over again for the cameras," said Hughes, who can be seen on the YouTube clip from the episode. "He was sweating so profusely that in-between takes someone had to run up with a blow dryer and dry him off. But he did it perfectly every time. He never complained. He was amazing."

Hughes also was amazed by Darren Criss, who plays Blaine Anderson, another member of the glee club.

"During breaks in the filming of the ‘West Side Story’ episodes, he’d come over to us, the musicians, and he’d start playing the piano. Or he’d ask a girl if he could play her violin and start playing that. He can play just about any instrument and sight-read music perfectly. I talked with him for a while. He’s really talented and a nice guy, too."
