The song reached number 4 on the Billboard pop chart in August to be Wonder's eighth top ten hit.

[2][3] Tamla Records founder Berry Gordy listened to the song, and he thought it could be improved with more development.

On November 17, the horns and strings were added at Golden World Records, one year before it was acquired by Motown.

Motown promoted "I Don't Know Why" enough that it peaked at number 39 on the pop charts in March 1969, but many radio deejays were also flipping over the record and playing "My Cherie Amour".

[3] Wonder fell off the Hot 100 chart in April and most of May, but fan response to "My Cherie Amour" was building, and Tamla re-released the song for radio as the A-side.

It should score in tab, easy listening markets as well as pop and quickly surpass sales of the original side.
