Composers' Forum-Laboratory Concert Entered from New York Times concert listing and review. Some selections noted in the listing are not mentioned in the review, and vice versa, so the exact program is uncertain. Also, although Richard Singer is named as the pianist in the listing for Morris Mamorsky's "Dance Sonatine", the review does not mention his name; instead, it suggests that Samuel Yaffe may have been the pianist for this work.
