A banjo-clad Dave Matthews dropped by the Sesame Street set to cheer up his fuzzy, blue friend with a song called “I Need a Word.”

A clip for the episode, the season premiere which airs 16 September, shows a bummed out ‘David’ relating to an equally down-in-the-dumps Grover trying to cope with bad feelings through the positive energy of music.

Shining moment: Grover harmonizing with Dave in that Grover voice. Watch below.
