Last night, two guitar greats in Tom Morello and Warren Haynes were able to share the stage at a very special benefit concert, The World On Stage. Hosted by Global Citizen at the NYU Skirball Center, the event featured a number of powerful discussions about solutions to global problems, mixed with moments of incredible live music.Among the many highlights from the night was the collaboration between the two guitarists, along with vocalist Regina Spektor and Jon Batiste, who was playing a keytar. All four incredible musicians joined forces for a cover of The Beatles’ classic “While My Guitar Gently Weeps.”Watch the group in action, courtesy of Andrew Work Uploads on YouTube.The song choice made sense, as the event featured Paul Simon giving out the first-ever George Harrison Award. You can see Simon also play a rendition of another Harrison classic, “Here Comes The Sun,” below.Amazing! What a treat to see these talents coming together for such an important cause, celebrating charity on the global scale.
