Super Junior
On April 29, 2008, it was announced that Super Junior-T would make a comeback later in the year with their second single. However, a fourth Super Junior sub-unit, Super Junior-Happy, debuted instead, putting Super Junior-T in partial hiatus. Nonetheless, Super Junior-T remained partially active throughout the year as they still appear as a group in Super Junior's concert tour, "Super Show" and other similar functions. Despite the debut of Super Junior-Happy, a future full-length album is still in the works and is expected to arrive in the future. Super Junior-T's latest appearance before the debut of Super Junior-Happy was on May 17, 2008, performing as the opening act at the 6th Korean Music Festival in Los Angeles, California.
