After a spirited performance by Janelle Monáe and a string of nostalgic No. 1 hits by Chaka Khan (“I’m Every Woman,” “I Feel For You”), the headliner who attracted the sold-out crowd sauntered onstage. Nervous as ever, singing in front of her largest crowd yet, Adele hid her eyes, giggled and even forgot some of the words to her own songs. Continuing down a lane first traveled by Amy Winehouse, Adele charmed the crowd with her cell phone call to her mum back home in Wales and wowed them with her phenomenally soulful voice as she belted out crowd favorites “Hometown Glory,” “Cold Shoulder” and “Chasing Pavements.”
