Dave Hill and Don Powell are still doing the rounds as Slade.
Very much doubt Noddy Holder and Jimmy Lee would want to join again as they both seem very happy doing wot they doez.
Last time I saw them would be some time in the 80s when they played The Odeon in Edinburgh and before that, Castle Donnington.
Would pay the money to go and see them if the origonal 4 were to tour again.
A very good rock band totaly underated.
