Stevie Wonder Sings ‘Happy Birthday’ in Middle of L.A. Restaurant

If Stevie Wonder doesn’t sing at your birthday party, did you even have a birthday??? That’s what some folks in an L.A. hot spot might be thinking after an impromptu performance.

This video’s about as cool as it gets … the legend was having dinner Thursday night with his son and some other family members at Teleferic in Brentwood, when he busted out his version of “Happy Birthday” — y’know, the cool one.

We’re told everyone in the joint stopped what they were doing to watch and listen to Stevie. You’ll notice very few people sang along with him … it’s not like anyone was gonna do it better.

Seems SW and co. were celebrating the birthday of his son’s mother-in-law.

Coincidentally, someone at a neighboring table also had a bday, and his pals had just finished singing the lame old traditional version.
