Chris Barron is a recording artist most well known as the frontman for the rock band Spin Doctors.

In 1996, Barron appeared on Sesame Street to sing "Two Princes" with Zoe, Telly and Elmo. He mediates a discussion between the three about how the three of them can all play together.

Barron later appeared on The Greatest TV Moments: Sesame Street Music A-Z to talk about his appearance.

Another of Barron's songs with Spin Doctors, "Little Miss Can't Be Wrong," was parodied for Sesame Street as "Little Miss Count Along," sung by The Count and Zoe.
