Such a great song and such simple, yet excellent advice.
Don' Worry Be Happy was the first ever a capella song to go to number 1, and won the Grammy for song of the year in 89.
The film clip features Bobby McFerrin hamming it up with famous American clown Bill Irwin and Robin Williams. It's such stupid fun that always brings a smile, which certainly can't be a bad thing.
Sure it might be a one hit wonder, but it cam make you forget about that busy morning, hectic afternoon or piles of work so kick back, don't worry, and be happy.
