This was billed as a tribute to Marvin Gaye and the 40th anniversary of his legendary "What's Going On" album. Unfortunately, the tribute was nearly non-existent. Sharon Jones of the Dap Kings sang "Mercy, Mercy, Me", and there was an ensemble song at the end, but that was it. The rest of the evening was two to three songs by a series of unknown artists, some were good, others will probably remain unknown. Then Stevie Wonder came out and did only two of his own songs. Perhaps the concert was better than my review, but it wasn't what I was expecting and it left me wanting for more.
