Sesame Street paid tribute to blues legend B.B. King on Friday by tweeting a video of his jam session with the show’s puppets, a song called “The Letter B.”

“Without the B, there’d be no Big Bird,” he sings. “There’d be no King B.B. But we do have the letter B.”

King died Thursday at the age of 89. “We mourn the loss of B.B. King,” Sesame Street wrote, “who taught us his favorite letter through his love of music.”
