I think you're right with Michael bass, suedan. 60 is a former pm of Australia. Could you give me clues for 36 and 55 please? Am finding this quiz challenging, to say the least. Haven't got any of the others you asked for, sorry
Suedan 31 is a 2000 Olympic swimmer, part of his name is a nickname.
38 is an actress whose surname can be found in any fish and chip shop. 44 is a boxer from around the 50's I think. His whole name is the name of a fish. 57 I can't really give a clue as I can't remember how I found it - Leroy Brown.
