When the news came out in the morning of 100818, it was not revealed which role Yesung would take. However, as somehow indicated on the casting poster, we can infer that Yesung is Sir Dennis Galahad.

All the roles of King Arthur, Sir Lancelot the Homicidally Brave, Sir Robin the Not-Quite-So-Brave-as-Sir-Lancelot, Sir Bedevere the Strangely Flatulent are taken, leaving only the questioning blank of Sir Dennis Galahad. Also, judging from the name tag of the rest of the cast, Yesung is not mentioned. He must be the surprise the production team intends to give to this musical.

On the other hand, I have just read an article on playdb.co.kr and it confirms that Yesung will be Sir Dennis Galahad. And FYI, Yesung is Sir Dennis Galahad - The Dashingly Handsome.

Quite worth looking forward.
