A series of song segments, directed by Jane Aaron and with music and lyrics by Christopher Cerf. In voice-over, singers would praise letters, which would pop up from the ground in animation or appear as pixellated props in live-action settings. The songs were registered according to the letter, i.e. "Big B and Little B" and so on down the line.

The series debuted in Season 26 with four songs ("B," "D," "R," "T") and four more were produced the following season ("C," "G," "J," "P").
