Jeff is the keyboard player, vocalist, he loves performing when he is awake. Jeff cannot help falling asleep, and when he dreams he dreams of being asleep.
Jeff says "The Wiggles is so much fun, only I use so much energy when I dance and sing that I get tired and I need my sleep,
sometimes I fall asleep on stage, but the children wake me up by shouting 'Wake Up Jeff'!". He wears a purple shirt, black pants and a multiple of wacky grins.
