As President Shimon Peres gave Prime Minister Benjamin Netanyahu the task of forming a coalition on Saturday evening, Yesh Atid party chairman Yair Lapid was celebrating the end of a successful campaign which won him and his party 19 seats in the next Knesset.

At a party in Netzer Sereni, a kibbutz in central Israel, Lapid thanked the campaign workers and activists who helped Yesh Atid become the second-largest party in Israel.

“We won,” he shouted happily as the crowd cheered him on.

During the event, Lapid took to the stage several times — not just to thank his supporters for believing in him and standing by him but also to ply guitar and sing several songs, including The Beatles’ “With a Little Help from my Friends.” He was joined by musician Rami Kleinstein and singer Einat Saruf, as well as comedienne Adi Ashkenazi.

Lapid also gave a more conventional speech, explaining his party’s surprising success.

“It’s a new world,” he said. “Facebook has replaced the town square. The old definitions of left and right don’t apply anymore.”

Lapid thanked his young voters, saying that in the 2013 elections, the youths had told their parents for whom to vote rather than the other way around. “These are the kids who told their parents, ‘Remember that your vote decides our future,’” he said.

“People voted for us because they believed we came to do good,” said Lapid. “They believed that we really did come to make a difference.”
