40. ‘What’s Happening!!’
The funky intro to 'What's Happening!!' made good use of the traditional 70s horn element by turning it into something off-kilter and wacky, just like its characters. It aired from 1976 to 1979 and focused on friends Raj, Rerun, and Dwayne -- three African-American friends living and working in the Watts area of Los Angeles.
