I was at the Rotterdam North Sea appearance. The video Brownie linked is one we all saw several minutes into the set as his sister and the band coaxed him out of the dressingroom. He stopped "Stand" midway, played and sang "If You Want Me To Stay", then facing the wrong way off his piano stool stared into (space?) for a while, was pointed back to the keyboard, got up, went to the front of the stage and said "I'm an old man. I'm gonna take a fuckin' break" and left for fifteen minutes, eventually returning for a very short set. The tragedy was that the band was absolutely great and his sister still sings very well, but Sly, the 'name' they need, was a mess. If this is indicative of his 'comeback,' he won't get away with it. The room was packed with people (ten thousand) at the beginning and people started leaving early on...
