Rock legend Don McLean took to Twitter on Saturday (Aug. 18) to share a video of him and Ed Sheeran singing a casual rendition of McLean's hit song "Vincent."   

In the video, the "American Pie" icon and the "Perfect" singer are seen sitting together backstage before performing at a UCLA Health and Teen Cancer America benefit concert. Sheeran is shown strumming a guitar to the iconic hit while he and McLeans take turns singing the verses, before coming together on the chorus.  

McLean captioned the post, "Ed & I rehearsing Vincent for the big show! Ed is a quick study...turned out great."
