it's surprising how few of these Motown actually released on DR. I'd also say it's odd the Supremes didn't have any, although their internal problems could have been a factor. but then again MW got a Red Hot release

i also think it's odd that the 12" releases were often just the same as the album cut - like on Love Hangover or Don't Leave Me This Way for Thelma. they didn't invest the time in remixing the track for a true dance/dj version

i don't have my books in front of me but i think the DR releases were:

Love Hangover
You're love is so good for me
What you gave me
Lovin, Livin, Givin
The Boss
No One Gets the Prize/The Boss

oddly enough i don't think they ever released an official 12" single for any of the chic songs. and did they do one for One Love In My Lifetime?
