Let's be honest, it is slightly baffling how Mr Hudson has become the go-to vocalist for Kanye West and Jay-Z when they need a big chorus on one of their many huge hits. If you found that confusing though, wait until you see what he has been up to in his time away from 'Ye and Jay.
Joined by Rosie Oddie, whose Dad Bill takes a night off from birdwatching to support from the back of the room, BIGkids are unashamedly pop - and not the Guetta sponsored club variety either. Wearing their signature paper crowns (think the kind you get in Burger King - literally) the duo are joined on stage by four bandmates, all of whom shy away from the more wacky look of the front two but add rhythm, riffs and er, saxophone to songs such as 'Good For You'.
Oddie is the main focus of the band, jumping around and pulling focus throughout. She gives it her all and is aware, perhaps a bit too much, that this band could launch her to a stage in her musical career that previous ventures promised, but failed to deliver.
For Hudson however, you must suspect this is just a fun sideline until he next gets the call from his A-List buddies across the Atlantic. Sat behind the keys all night he provides an edge that songs like new single 'Drum In Your Chest', an instantly catchy but relatively simple song, need.
That's not to detract from what BIGkids are all about though - good fun. Expect them to be busy owning every support slot and festival tent for the rest of 2012.
