That's the beauty of it, look at the "so solid crew", singing these days don't mean jack. What we need is gimmic's and lots of em'.
We could steal older groups stuff, how would you feel about ripping off your shell suit half-way through the act - Bucks Fizz stylee or maybe half-way through the song you could all get off your stool's at the key change like Westlife do. Think of the endless possibilities....
