Rarities from the Hollywood Studios 1933-1958 (2 CD Set) The 2 CD set of previously unavailable tracks are taken from studio playback and movie exploitation discs or alternative versions from 1933 to 1958, spanning 25 years of Bing Crosby's career. The contents of both CDs were produced by and for the film studios for differing uses in the making of the films and the records themselves were never intended to reach the hands of the public. These unusual and rare tracks have been remastered and sound amazing.
