"Hello Hello Song" is a Sesame Street song that closes the DVD video, Making Friends. Elmo and Professor Grover sing the song to their students as they arrive for school today, introducing themselves and getting to know the kids' names as well. The first verse was later sung by the Sesame Street Muppets (including Elmo, Abby, Big Bird, Grover, Cookie Monster, Ernie, Bert, Rosita, Murray and Zoe) in a special video created for the Sesame Workshop office lobby.
