I was invited to sing at a benefit concert in Paris in 1964. At that time there were thousands of Jewish students from Algeria and Morocco who had nothing to eat. Some people together with Baron de Rothschild organized a kosher kitchen to give them one meal a day. To raise money for the food, they organized a concert once a year and made $100,000 from the ticket sales. Baron de Rothschild donated the rest of the money needed to run the kitchen.
During the concert Baron de Rothschild was sitting in the front row. I said to him, “You support the world with a lot of money. How about bringing joy to the world one time. Can you please come on stage and start dancing with me? Everyone will then dance after you.”
He jumped on the stage very gracefully and sweetly and we danced out onto the street. The police saw Baron de Rothschild dancing and stopped the traffic. The concert hall, which was one of the biggest in Paris, emptied out onto the street. I would estimate that 2,000 people were dancing with us on the street. It was one of the greatest nights in my life.
(Sadly enough, Rebbe Shlomo and Baron de Rothschild didn’t keep in contact, but that night remained in the hearts of both of them.)
