Sesame Street has released three veteran characters of the long-running children programs but it appears they have all had a pretty good run. Bob McGrath, who has played Bob the music teacher on the show since it premiered in the 1960s, Roscoe Orman, who plays Gordon the science teacher and Emilio Delgado, who plays Luis, as Mr. Fix-it are all now gone. They are veterans of the early 70s. McGrath is 84 and said he has been “:graciously let go” from the Muppets Cast podcast. The program moves from PBS to HBO in coming months. Toronto Star
