[OT] Stevie Wonder - Which is the A-side?

Neither of these made the Hot 100, let alone the top 40, but maybe someone here can answer which was the intended A-side. I've used Google, 45cat, and Discogs, as well as consulting the Complete Motown Singles Box sets. There doesn't seem to be a solid consensus and/or definitive reason for picking one side over another for these two:

Tamla 54070
Little Water Boy (DM V-007112) / La La La La (DM B-008103)

Tamla T-54103
Sad Boy (DM 11L-093301 RK4M 2335)/ Happy Street (DM AQL-093304 RQ4M 2338)

While one side of each 45 has a higher matrix number (in parenthesis above), neither are sequential and also have different letters, so again, it's not as obvious to me by looking at those.

Discogs says "Sad Boy" and "La La La La." 45cat says "Happy Street" and "Little Water Boy," but I believe this is based on the box set track lists and were at one time swapped. TCMS puts "Little Water Boy" and "Happy Street" first in their track lists. The matrix numbers for "La La La La" and "Happy Street" are higher, which could potentially mean they are the intended B-side. Neither of the promo 45s have a starred or "plug" side. Clear as mud.

Good observation, Ron!

I think it's most likely that "Little Water Boy" is the A-side, because two sources from the time list it first. This Billboard 10/20/62 listing of songs with Moderate Sales Potential:

Also, 45cat has an image of the Cash Box review of the single, and it also lists "Little Water Boy" first.

Outstanding detective work, Brian. I think you’re right that the A-sides are
“Little Water Boy” and “Sad Boy.”
