Dear Mr. Ronnie,
I trust you have received our invitation to our Annual Dinner at the K.L. Hilton on Saturday 25 October at 7:00 P.M. I have a favour to ask of you.
My staff has pestered me to ask you to give a speech on marketing strategies in the new century as they say you are the best in the field. I agree with them on that. So could you give a short speech at the Dinner on the subject (or any relevant subject)? We would be most grateful if you could. Please let me know of your answer. Thank you.
