Dutch national broadcasting service NPS will be broadcasting from the North Sea Jazz festival being held in Rotterdam this coming weekend, where Jamiroquai perform on Friday evening (scheduled to be on stage at 18:30).
I don't know exactly if and how much Jamiroquai will be broadcast on television or radio but more information about the festival broadcasts is available at the NPS website.
