Dear Tom and Len, Regarding Len's query: >PS. Heaven's to Mergatroid? Did you spell that correctly?< Tom almost got it right. "Heavens to Mergatroyd!" was 'coined' by the Hanna Barbera TV cartoon cat 'Snagglepus' whose other famous catchphrase was "Exit stage left!". Kind regards, Bill (who is not just a jazz 'know-it-all').
