Menudo

Menudo is a Puerto Rico-originated boy band that formed in 1977, with different members floating in and out of the group through 1997. A new line-up was briefly active from 2007 to 2009. Among the most notable members of the group were Draco Rosa (1984-87) and Ricky Martin (1984-89).

The group — consisting of members Robby Rosa, Roy Rosello, Charlie Masso, Ricky Martin, and Ray Reyes — appeared in two scenes on Sesame Street during season 16. They performed a variation of their hit "Gotta Get on Movin'" (First: Episode 1971) and gave a demonstration of the word "AGUA." (First: Episode 1997)
