[Typo3] julle_events changing html output

[Mike Fabricius]

I am trying to customise the julle_events extension. I would like to 
alter some of the field names which are displayed in the front-end to 
users who are registering. Specifically, company -> club, and city -> 
location.

I can't see these items listed in any on the locallang files.

Does anyone have any ideas? I couldn't find anything on the list.

Thanks for your help,

Mike
