Thinking about songs recorded by Michael Jackson and/or The Jackson 5 that were later covered by other Motown artists.

Some examples:

"i Want You Back" - David Ruffin
"I'll Be There" - Four Tops
"Never Can Say Goodbye" - The Supremes
"Got To Be There" - Smokey Robinson & The Miracles
!I Wanna Be Where You Are" - Jose Feliciano

What else?
