They are in fact three members: a pianist, a drummer and a bassist. They remind me a lot of the early Elton John Band when he was touring with just Dee Murray and Nigel Olsson. They are very energetic. I particularly recommend their second album, Whatever and Ever Amen.
Jon's Elton is a musical tribute to Elton John which is really spectacular, featuring a computer-controlled light show, state of the art sound system and top quality costumes made by one of Britain's top costumiers.
