Which music artist is credited for singing, producing, and recording "Mercy Mercy Me (The Ecology)"?

Loved Marvin Gayes music!

What a tragic end to his life at the hands of his own father. Loved his voice, Oh, Mercy, Mercy, Me, What's going on???

Marvin Gay was in a very creatively spiritual space when he composed that album. All of the songs are magnificent. "What's Going On?" never gets old.

Yaz, just one of many r & b artists from that time period whose music is still relevant in this current time period there music unlike today's artists transcends from generation to generation even my daughter enjoys the Motown sound along with some pfunk

loved his singing, such a sad ending

A song that always makes me turn up the volume.

He had some great tunes he sung back in the days. May he rest in peace.

A voice that reminds me of honey...smooth and sweet

I loved his music!!! Dang dad wht the heck!!?
