Ed Sheeran performs at Notre Dame Academy in Hingham

“Give me an E!” a kilt-wearing Notre Dame Academy student screamed to her fellow students, who shrieked back in unison. “Give me an D!” she continued. “What’s that spell? Ed!” It was a short call-and-response session, but it was deafening. The almost 550-plus students at the all-girls school in Hingham squealed with anticipation until English singer-songwriter Ed Sheeran took the auditorium stage to sing a few songs, including his radio hit, “The A Team.” Sheeran performed the after-school concert for Notre Dame because the school won Mix 104.1’s “Koats for Kids” contest — a coat drive for the Big Brother Big Sister Foundation of Boston — by collecting 2,770 coats. The Notre Dame drive was led by three students: 15-year-old Abby Rouleau, 17-year-old Marissa Gildea, and 18-year-old Hannah Paradise. Paradise explained that she discovered Sheeran on YouTube about a year ago, “and I fell in love, like right away.” Sheeran met with the three young women, and spoke to us just before taking the stage. He admitted that it’s been a wild year in the US. On Jan. 30, 2012, he played New York’s Mercury Lounge, which fits about 250 people. On Jan. 30, 2013, he headlined Radio City Music Hall, which holds 6,015. Sheeran said he’s preparing for a summer tour with Taylor Swift, which will bring him to Gillette Stadium, a venue with a slightly higher capacity than Radio City. “60,000?” he guessed, grinning sheepishly. “We’ll see what happens.” When Sheeran finally took the stage, he told students that there’s also a Notre Dame Academy where he’s from. At least, we think that’s what he said. It was difficult to hear him over the screaming.
