I'm delighted that a Spanish name has come into the discussion at last. Flencomo guitaritsts I cannot even put a name to have excited me just as much with their ability as Tony has. I've in my time shared a stage with Tony McManus. He is indeed astonishing, and currently the best I know of in town at what he does. But I'd never think of allocating anyone the title of 'the best' Scots guitarist even. It depends what you think is important. This debate seems to think that accuracy, speed, and deftness are highly important cum crucial. How about soul, originality, character, innovativeness, variety, sensitivity to the tradition, etc, etc. I'm in the midst of reading J F Chernoff's 'African Sense and African Sensibility', and have just read an interview with Dagomba drummer Ibrahim Abdulai in which he talks about the speed and energy that younger drummers employ. But they eventually get older and learn what else in important in music. By the way, who is the 'World's Greatest Singer', then?
