This is a slightly weird(but good!) clip of Paul Simon singing "Me and Julio" on Sesame St. in 1972. The strangeness comes from the little girl who duets with him. She's pretty cute actually, as she improvises her own lyrics to the song. But it gets super awkward around the 30 second mark where Simon breaks in and starts singing the actual song. It makes him seem kinda like a jerk for a second, upstaging a little kid!
The little girl takes it in stride though and actually takes turns harmonizing with Mr. Mrs. Robinson. It's pretty sweet.
