After Sheeran's bluesy "Thinking Out Loud" -- which paired the UK singer-songwriter with guitarist John Mayer, jazz legend Herbie Hancock and The Roots/Tonight Show drummer Questlove -- he joined the classic rock group for one of their signature hits. 

But before that, Lynne's ELO performed a bit of "Evil Woman" on their own. Paul McCartney was clearly delighted to have a vintage hit at the Grammys -- the live feed captured him singing and clapping until he realized he was on camera and sheepishly sat down. 

After that, Sheeran joined ELO for the immortal "Mr. Blue Sky. With Lynne and Sheeran trading vocals on the transcendent epic, it was a throwback Grammy moment that truly worked.
