With celebs manning the phone lines, the Hand in Hand: A Benefit for Hurricane Relief Telethon generated over $44 million in aid, according to event organizers.
But what were the stars doing when the cameras weren’t watching? PEOPLE was on-site in Los Angeles at Universal Studios (the telethon was also held in New York and Nashville), where everyone from Barbra Streisand to Justin Bieber was doing their part.
“Bryan Cranston was behind me. Oh my God,” said Robinson. “And while Stevie [Wonder] was singing ‘Lean On Me,’ and Charlie Wilson was behind me jamming, it was just like, Oh my God, overwhelming.”
Added the actor, “Jay Leno was cracking jokes, of course, but the phone just kept ringing, so it wasn’t really — so that was before we started answering the phones, before they starting ringing, and then it was all business.”
The entire event came together seamlessly, Scooter Braun – whose SB Projects was one of the organizers – told PEOPLE, with the star-studded group of participants more than happy to help out.
“I was struggling to find a performer in New York, not because people didn’t want to do it, but because of scheduling, and I threw a Hail Mary to Dave Matthews,” admitted Braun. “Dave Matthews was in Seattle, and Dave Matthews – with two days to go before the event, he said, ‘It’s the right thing to do. I’ll fly in.’ And he flew himself from Seattle to New York to perform that song.”
Braun championed the “kindness of every single person” who agreed to help out.
