LONDON, Sept 25 (Reuters) - Britain's competition

regulator has secured formal commitments from Ticketmaster to

ensure customers have the information they need when they buy

tickets from the entertainment and event group's platform, the

watchdog said on Thursday.

Thousands of fans waited for hours online to get their hands

on tickets for the British band Oasis's reunion shows this

summer, only to find prices had jumped by the time they got to

the front of the queue.
