It will be the Masterwords edition (with the alternate tracks) with the addition of some extra bonus materials.
The first release (on Columbia) is the only CD version that duplicates the original LP release.
I like most of the changes and additions Thomas Sheppard did for the remaster. It was great to hear the extra music in "Gimmick" - which should never have been deleted from the original Lp release. Merman's slightly different reading of one line in "Rose's Turn" and the addition of Louise's giggles in "All I Need is the Girl" are not intrusive. I could live without the extra strip music in "Let Me Entertain You" or the extra drums and cymbals in "Dainty June and Her Newsboys" but overall I find the remaster an improvement over the original.
It makes me wonder, will we see a 50th anniversary edition of SOUND OF MUSIC this November? BYE BYE BIRDIE next April? CAMELOT next December?
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
