I would love to see a conversation between Bill Cosby and Dave Matthews.
Think about that for a moment. Shambling, gravelly, and, above all, humorous. Both have distinctive speech patterns that would play well with each other. Both Dave and Bill do great impressions of grumpy old men.
Btw, just got news today that Dave Matthews Band is scheduled to play at the 10,000 Lakes Festival in Detroit Lakes, Minnesota, this coming July.
