i went for a birthday treat with my mum and auntie, also my son and i was waiting for barry manalow to come on, i was mislead by the advertising of my tickets which said . Barry manalow's copacabana. I wasted £70 and was upset , i would never have gone if i'd have known. When i saw Diana Ross on my tickets i actually saw her when i got tickets for Whitney i actually saw her, so why was this ticket allowed to say barry manalow on it. i am not the only one who got confused by this, several others in their was upset too. !!!! ruined my birthday.
