I was expecting to see a show where they just stand around and sing slow songs. WRONG! It was so upbeat it really blew me away. I was not expecting to see them do fast paced choreographed dances. They rocked out! Bob Marley, Prince covers! Country music! Motown! Plus all their old favorites we all know and love. Also, their little comedy bits were unexpected too. Boyz I I men brought their A game to Vegas! Well worth the money. I only wish they had a residency there. They kicked ass! P. S. If you think their voices would sound tired and dated, or different than you remember... N-O!! They sound exactly the same if not BETTER than you remember from the radio or a cd. Their voices still amaze and harmonize like better than ever before!
