Once the girls hit with WDOLG, we all know that HDH became their primary production team. at least for the pop songs [[other producers did the early concept albums).

during 2nd half of 64, they only recorded a couple non HDH tracks [[again aside from the concept work)
*Ooowee Baby with Smokey
*Come into my palace with Mickey

in 65 they also only did a handful of tracks
*Take me where you go with Smokey
*Too much a little too soon with Smokey
*Slow Down with Clarence Paul

But then in 66, they did a ton of work with other producers:

*Frank Wilson and Hal Davis - It's Not Unusual, Get Ready, This old heart, hang on sloopy, money, shake me, Satisfaction, Mickey's monkey, Uptight, These boots, Can i get a witness.

*smokey & frank they did Misery Makes Its Home

*William Weatherspoon - what becomes of broken hearted

*Slow down [[again) with Clareance Paul

*Just a little misunderstanding - clarence and mickey

*come on and see me with ivy jo hunter, harvey fuqua and johnny bristol

*with a child's heart with Hank Cosby


I find it surprising that during a peak period [[spring and summer 66) when the girls were still hot with HDH that they did so much work with others.
