The Bel Canto Society print of Carnegie Hall is the only one that is complete, with all the musical selections. The currently competing version is missing Lily Pons"s "Vocalise" (Rachmaninoff) and more than half of Bruno Walter"s Meistersinger prelude. Moreover, although that version announces Rise Stevens in "Mon coeur s"ouvre a ta voix" (Samson et Dalila), it omits the selection and jumps to the next one. The Bel Canto Society version includes these selections complete and all others. The Bel Canto Society version has PCM audio, with the transfer from analog to digital using the Lavry Gold converter. The competing version has Dolby Digital audio, at 192kHz, which omits 87 percent of the sound.
