Not an answer but a question.
I've completed my Sir Lancelot crossword 18.05.08 and it doesn't have either of these clues. What part of the world are you in?
My apologies - I was alsmost asleep when I was doing both Sir Lancelot and the Sunday Telegraph and got both mixed up - I am truly sorry but with 72 years behind me I'm allowed at least oner lapse! Thanks to you all and kind regards.
