Really, it wasn't all that challenging. The song had an exceptional number of key changes, and layered harmonies, but it was hardly Sondheim- at least, that's how Ricky found it as he joined in with his part, glancing over at Kurt and grinning. Really, even he would admit it's about time the guy had a solo..and he seemed to be doing quite well with it.
Though, a few dance steps would definitely make things glitzier, that was fore sure.
