No, it's not a well known one. Basically Capital FM (the leading commercial station in the UK) have their annual Balls at Wembley which are well established & attract top pop names - including international acts. Key 103 is trying to leverage this type of popularity for a local event in the North West. But as you can see from the calibre of the acts - with only Louis and Rita having truly international fame - it's a pretty provincial affair. Very Syco heavy too. Glad he's getting promo though.
