This one is easy as pie! THE BEST happy song of the moment is Martha & The Vandellas – Dancing in the Street. Great Motown song written by Marvin Gaye, covered by Mick Jagger and David Bowie for Live Aid in the 80s and just a great pick-me-up-and-put-a-smile-on-my-face song. Now including super retro video. Enjoy!
