Derulo isn’t alone in the hip-hop world in this situation, but it still mars some of the enjoyment, when 2013’s “Wiggle” includes the lines “How do you fit all that, in them jeans?/ You know what to do with that big fat butt/ Wiggle, wiggle, wiggle”; and his mega hit “Talk Dirty” has the lyrics “Dos Cadenas, close to genius/ Sold out arenas, you can suck my *****... Got her saved in my phone under ‘Big Booty.’”All the more so when the crowd is exclusively young people from around the country – his messaging leaves much to be desired. But I can’t deny his catchy hits and palpable zeal made it an incredibly fun evening.In addition to selling tickets, the festival, sponsored by Coca Cola and produced by Live Nation Israel, gave away 8,000 spots to teens who took part in volunteer activities around the country.Derulo’s boundless energy kept things going with his hits “Swalla,” “Trumpet” and “Ridin’ Solo” before closing out the night with “In My Head,” “Talk Dirty” and “Want to Want Me.”The singer departed after 1:30 a.m., but the party kept going until 5 a.m. with several more local acts and artists. But since I’m not 15 anymore, that was my cue to leave.
