Dunno if it's the same bloke but we had a Rod Stewart look-a-like staying at Seastar in 2011. Lovely story. One night he was sitting at the bar and we didn't really want to bother the guy because he's probably bothered all the time. The second night a friend of ours took the stool next to him. He stared at him, took a sip from his Efes and said to him that he reminded him of someone but couldn't his finger on it. He took another sip from his Efes, thinking very hard and suddenly shouted: "I know, you're Robbie Williams!" I nearly fell from my stool laughing. It resulted in a great night though because he could sing like Rod as well. Quite well actually. I've got a great picture of him but don't know how to upload it here.
edit: found it (ain't so hard)
