Everest prospered for only a few years. The label may have been hurt financially by Whyte's recording the complete Pablo Casals Festival in 1960. By this time, Harry Belock owned only 22% of the business and the board removed him from control. Belock (who died in 1999) left the record business and sold his interest in Everest to his accountant, Bernard Solomon, in 1962. The studio and all its recording equipment was sold in 1961 to engineer C. Robert Fine, who used the equipment for Mercury Records, Command Classics and other recordings. A Mercury CD release by Robert Fennell of Gershwin and Cole Porter (434 327-2/1993) contains the following information on the inside of the booklet: "The songs of Cole Porter were recorded in the Bayside Studio of Fine Recording, N.Y., on November 20 and 21, 1961, on 3-track 35mm film, 3-track half inch tape, and 2 track quarter-inch tape..on this CD the 3-track half inch master was used as the 35mm was unavailable." This would indicate, if true, that Mercury Records had commenced 35mm recording using at least some of the Belock equipment in late 1961.
