69-year-old Swapan Sett plays the violin at Shiv Sagar restaurant in Girgaum, Mumbai, at lunchtime. For 15 days each month, Sett travels from his home in Kolkata to a different Indian metro so he can sell his music at popular restaurants and temples, each CD priced at Rs 150. The money he earns helps pay for the twice-yearly cancer treatment his wife Purnima needs. She was diagnosed with uterine cancer in 2002. Sett says that in today’s day and age, money comes and goes, but if two people speak to each other with courtesy and affection, it’s priceless.
