The passing of longtime Sesame Street performer Bob McGrath has left many in mourning. Along with fans around the world who have memories of McGrath from watching Sesame Street in their youth, there are others from within the world of Muppets and Sesame Street who are also feeling the sting of the loss. This includes Kermit the Frog, with whom McGrath once appeared in a very memorable sketch to talk to the Muppet about frogs croaking. McGrath also sung a special rendition of “The Rainbow Connection,” a song made famous by Kermit.

On his official Twitter account, Kermit the Frog shared a message honoring McGrath. The tweet encourages fans to sing a song for the late entertainer to help remember him, feeling that this is only appropriate given all of the times he’s done to so entertain young viewers watching Sesame Street.

“There was no one quite like my friend Bob McGrath,” the tweet reads. “His infectious joy and remarkable voice could make every day sunnier. I’ll always remember the wonderful times we shared on Sesame Street. Let’s all sing a song for Bob today.”

She also describes him as someone who couldn’t have been any nicer to her and her sibling.

The tweet reads, “I first met Bob McGrath in 1969 when he & my Dad Matt starred on Sesame Street. He was the nicest, sweetest, kindest man. My brother and I got to be in this scene with him… Rest in peace, Bob McGrath. You were so loved all over the world Say hello to my pops.”
