Going back to the point sternth made to start the thread, can anyone help supply information for five mystery records in the Stinson series?

So far we don't know who made these records, or what their titles are.

SLP 49
SLP 68
SLP 72
SLP 75
SLP 89

Among these may possibly be (titles approximate):

Richard Dyer-Bennett German Songs of Beethoven
Mary Lou Williams Selections From the Zodiac Suite

Can anyone help???
