Today we honor Martin Luther King, Jr.  by sharing Stevie Wonder and a slew  of stars and celebrities singing “Happy Birthday,” 4+ minutes of aural energy and  joy.

As one of the song’s “comments” on YouTube put it:  “Stevie should have a national holiday named after him for the pure joy and genius he has given the world.”

MLK, Jr.’s actual birth date  is Jan. 15.  Had he lived, he’d be 91-years old.
