[78-L] Release date needed

[David Lennick]

I may have asked about this one previously. Mercury SR 90282, 
Dorati/Minneapolis: Schuller "7 Studies on Themes of Paul Klee"/Fetler 
"Contrasts for Orchestra" was recorded in April 1960, but can anyone confirm 
whether it was issued before or after January 1, 1961? 90268 and 90269 show up 
in the December 1960 Schwann "New Releases" but those numbers are quite a bit 
lower (and I don't know what the cutoff date might be for records actually in 
the stores).

Thanks
