Delighted over the response to the odd-even car regulation formula on the first day of its implementation in the capital, Delhi Chief Minister Arvind Kejriwal chose to reprise British singer John Lennon's song "Imagine".
"John Lennon" You may say I'm a dreamer. But I'm not the only 1, I hope some day you'll join us. And the world will be as one," Kejriwal tweeted.
