The upcoming wedding of HDFC chairman Deepak Parekh's younger son Siddarth with hotelier Claire O 'Neil is the talk of corporate circles these days. "Have you got the invitation?", "What are you going to wear?" are the most-asked questions in the financial capital's cocktail circuit, a chief executive visiting Delhi said. "Everything else has taken a back seat," he chuckled when asked about his businesses. The three-day wedding celebrations scheduled next week in the exotic Mehrangarh Fort in Rajasthan have caught the imagination of the corporate world with its cross-border romance and multi-cultural itinerary with Hindu and Christian ceremonies lined up.
