Regarding the release date of this 45, I'm not certain - but if this site is accurate:
https://www.jazzdisco...hy-1966/#660707
Then the recordings were done in July 1966 in NYC
It also states that there were two release numbers for "Morning morning":
Richie Havens (g, vo) and others NYC, July 7, 1966
100810 I Can't Make It Anymore Verve-Forecast KF 5022, FT 3006
100811 Morning, Morning Verve-Forecast KF 5022, KF 5039, FT 3006
* Richie Havens - Mixed Bag (Verve-Forecast FT 3006)
* Richie Havens - I Can't Make It Anymore c/w Morning, Morning (Verve-Forecast KF 5022)
* Richie Havens - Morning, Morning c/w I've Gotta Go (Verve-Forecast KF 5039 )
I've also just checked my 'records' and found that I've actually got a copy of 5039 - and what's more... it's also a demo!
This of course makes Palang's post (#32) not quite correct as there are actually 2 separate 45 releases with "Morning Morning" on.
Here's a scan of "I've gotta go", which was the side I bought it for in the first place.
But I still have yet to confirm the actual release date of the 45!
Just had another browse on that site and noted "I gotta go" as recorded on March 1st 1967 - still can't see any release dates for the 45s though...
