Bermudian singer Collie Buddz is due to perform in Boston tonight — but it was not known last night whether the concert would go ahead.Mr Buddz is scheduled to be on stage at the House of Blues but the city was under lockdown last night as police launched a manhunt for a suspect wanted in connection with Monday’s bomb attack in the city.Websites of both Mr Buddz and the House of Blues made no reference to the attack or whether the event has been called off, although another concert at the venue scheduled for last night was eventually scrapped.
