I must admit I've been singing this song in my Wiggleworms music classes - a parent/baby interactive music class at the Old Town School of Folk Music in Chicago. I've been singing this version. Of course, I'm giving Feist full credit so please don't sue me anyone out there. This version is great because unlike Feist's real 1234 song, the counting is accurate in the Sesame Street version. I'd hate to be sending babies into the world learning to count incorrectly. So anyways, it's a real hit in class for the indie-rock parents out there.
