C ...is for Cookie (1974 LP)

C ...is for Cookie! is one in a series of character-centered Sesame Street albums released in 1974. Although some tracks are from the earlier Columbia and Warner Brothers albums, some tracks appear here for the first time.

Later versions of this album replace "The Birthday Cookie" with "We'll Do It Together." That version of the album was also released as part of the 2-LP set Just the Two of Us. (Source: Muppet Wiki)
