Last week we asked who wrote, "Those who danced were thought to be quite insane by those who could not hear the music" – the words tattooed on the right flank of actor Megan Fox. Early guesses included "Angela Monet", Friedrich Nietzsche, and Sufi mystic Rumi.

Welsh poet Dannie Abse, winner of last year's Wilfred Owen Poetry Award, emailed to suggest "the 18th-century Jewish mystic Rabbi Nachman" was responsible. While "Bob" cited a translation of Henri Bergson's Laughter. Literature student Simi Freund thinks it can be "attributed to George Carlin, an American comedian who died in 2008". Can anyone settle this ?
