Not really because Stunner was already being booked to perform in the UK even before Stunner hooked up with Olinda Chapel. So Stunner never needed Olinda Chapel for any publicity because Stunner's name was bigger than Olinda Chapel's name.
Now back to this Zim Hip Hop artist Tricky J. Has Tricky being a Zim Hip Hop artist ever been booked for any Zim Music Fest in the UK the way people like Stunner, ExQ, Trevor Dongo, Killer T, Winky D etc are booked to perform live? That shows you how even the promoters in the UK don't see Tricky J as being a top Zim Hip Hop artist or having enough clout to pull a crowd.
