Enterprise

Some discographies list a single by O.B. McClinton with a catalog number of ENA-9113 (I Want You In The Morning b/w Short Red Dress), but this has never been confirmed to exist (a search of the Catalog of Copyrights turns up nothing.) While it is entirely possible that this was a projected single that didn't make it out before the label folded, this info should be taken with a grain of salt as no source for this info is given in any of the discographies that list it. (No recording of the b-side is known to exist.)
Additionally, some discographies give an a-side called Little Boy Blue to ENA-9110 (also by McClinton.) In reality, the a-side to that single is a song called The Most Wanted Woman (Is An Unloved Wife). A McClinton song by the name of Little Boy Blue remains to be seen.
ENA-9110 appears to be the last single released by Enterprise, and would've come out in January of 1975.
