“Glee’s” Chris Colfer is having fun with the yoga hammock with which his Kurt character does tricks on the show. “I’m hoping that gets incorporated into a number. I really would like to have themes for every performance,” he says. Colfer says he’s always thinking of songs he’d like to perform on the series — classic tunes and new ones as well. However, he says, “The main ones that I wanted to do are done. ‘Don’t Cry for Me, Argentina,’ ‘Defying Gravity’ and ‘Never Can Say Goodbye.’ All of those are done, so I’m very happy with that.”
