Dear [ ]
Many thanks for your gracious invitation to address the [Association of City Councils] at its annual convention. I would gladly accept were it not for the fact that I will be [in Bombay during that month evaluating their city services].
May I suggest my colleague, [Professor Jack Bruce, who has assisted me in much of my research into urban areas]. [Professor Bruce] specializes in [the human side of urban planning. While his focus is different from mine, we share the same basic philosophy.] I think your members will find his view equally interesting.
[Professor Bruce and I share an office,] and you can reach him at [the same number]. I will mention that you may be calling about a speaking engagement.
Best of luck on your convention. I hope it’s a successful one.
Best regards,
