Then there are cast recordings that have changed when they were reissued as CD's....
1. KISS ME KATE - The Sony Cd uses a longer takes of "We Open in Venice", "I Hate Men" and "Too Darn hot." (As originally recorded these songs may have been too long to fit on 78-RPM records.)
2. MISS LIBERTY uses many alternate takes. Though the dialogue lead-ins are the same they are read in a much more declamatory fashion.
3. GENTLEMEN PREFER BLONDES also uses alternate takes and ads some dialogue and musical segments that were not heard on any previous release.
4. THE PAJAMA GAME - for both CD releases an alternate take of "7 1/2 Cents" us used with poor Stanley Prager's voice giving out due to hoarseness. That did not happen on the take used for the Lp release.
5. BELLS ARE RINGING - on the Sony reissue they discovered a section of the master tape for "I'm Going back" was damaged so for about 30 seconds the track switches to a mono alternate take then back to stereo again.
6. DAMN YANKEES! - The RCA Victor CD restores a few dialogue lines left off the original LP release.
7. GYPSY - Several alterations were made for the Sony Cd including restoring a section of "You Gotta Get a Gimmick" that had been edited for the LP release, restoring an alternate take of the last half of "All I Need is the Girl” so we hear Louise giggling, adding some extra stripper music in "Let Me Entertain You" and using an alternate take of "Together Wherever We Go."
8. 110 IN THE SHADE adds the Overture that was not heard on the Lp. (It was never intended for release. The orchestra recorded it once so the engineers could check levels.) Actually the record does open better with "Gonna Be Another hot Day."
9. JAMAICA - RCA Victor's original cast recording has had a curious history. It was made just as the labels were transitioning from mono to stereo recording. At that time it was not possible to fit as much material on a stereo 12-inch LP as on its mono counterpart. RCA Victor issued JAMAICA in mono as LOC 1036 containing all the show's songs but leaving out the Overture and editing out the introductions to "Savannah's Wedding Day" and "What Good Does it Do?" A few months later a Living Stereo release came out as LSO 1036 and including the Overture but dropping 4 songs ("Pity the Sunset", "What Good Does it Do?", "For Every Fish" and "Savannah (Finale)") These issues were deleted in 1961. In 1965 RCA Victor re-released JAMAICA in mono and stereo as LOC/LSO 1103. Now, LOC 1103 was a direct reissue of LOC 1036. BUT...are you following all this? ... LSO 1103 had all the songs, including the extended versions of "Savannah's Wedding Day" and "What Good Does it Do?" but like its mono counterpart, left off the Overture. The 1995 RCA Victor CD release had the complete song program and the Overture. That CD sadly is now in cutout limbo. A new edition (paired with PORGY AND BESS) reissues the program as heard on the 1965 stereo LP edition (LSO 1103) and is missing the Overture.
10. Many Decca cast albums were complete on 78 RPM but truncated to fit early Lp releases and have only been fully restored for the CD editions. OKLAHOMA! was missing 3 songs on LP, CARMEN JONES was missing 2, UP IN CENTRAL PARK was missing 1 song, SONG OF NORWAY had introductions lopped off 4 tracks and made internal edits in two others, and BABES IN TOYLAND was reduced from 10 songs in the 78 RPM album to just 6 on the 12" Lp release.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
