Roar Katy Perry Download 'Roar' on iTunes
All Night Long star Lionel Richie led a singalong as he spoke to a group of Oxford University students this week!
In a Q&A session after his speech, the 63-year-old was asked to sing - so he chose to get everyone to sing The Commodores' Easy with him.
Lionel was impressed, remarking: 'Let's see how fast that gets to Youtube!'
Well Lionel, it took around a day… Here it is!
