Unallocated catalogue numbers.

[Roger Polhill]

In light of the recent unreleased tracks from Hattie Littles and LaBrenda Ben on Gordy is there a possibility of an album being envisaged but not decided on as there are four catalogue numbers unallocated: G.904,905,909 and 910 all around the time frame.
Also with T. 235 and Singin` Sammy Ward. Any suggestions?
