We just got off the Fantasy yesterday (8/11). The Caspians were there all week (great group- we enjoyed them too!) but that was there last cruise for a while. Tim Ashead is there and he does piano tunes. He did a tribute to Elton John one night. He is very good and friendly. Nice guy... He was performing in the Outlook lounge. Beautiful but sadly, it is above the Tween hangout "Edge" and the music/noise was very loud coming from there. Still a great view!
There was some other entertainment in the District each evening. You have to check the Navigator each day to see who is scheduled.
