Can anyone pinpoint an issue date for Columbia CL 810, Richard Rodgers conducting the New York Philharmonic? Per Gart, CL 820 dates from February 1956..just wondered if there was a more accurate date for 810, or if it had a previous life as an ML Masterworks release. Matrix numbers are XLP 34520/1 and the program material is derived from a benefit concert, November 15, 1954 (probably recorded shortly thereafter).
