I came to FOLLIES through the OBCR first when I heard it on a weekly radio program,. In those days (1970s) radio stations would often devote an hour or two to playing COMPLETE original cast recordings on the air. Sometimes the announces would even explain the stories as we went along. When I got the album was was puzzled that half of the songs were marked with a * and footnote indicated "some songs have been abridged for recording." When I got the script from our local library I discovered that 4 had been completely omitted as well. But what WAS on the LP was fascinating and I loved that record.
Like PJ I grabbed the live tribute album to hear longer versions of some songs (and the intriguing cut number "Pleasant Little Kingdom") but it wasn't until the 2 LP set of the 1985 concert came out that I finally got to hear the full score.
The 1987 London cast mucked about with the songs (and the overall tone of the show) too much, but the 1998 Papermill Playhouse album was note-complete and filled out with many of the cut songs.
None of these albums is 100% entirely satisfactory, although the sheer excitement of the Concert version makes it my personal favorite. Still I would never be without the original cast. Get Ted Chapin's fascinating book for am in depth behind-the-scenes look at the show's creation and details of the battles album producer had with the management at Capitol who refused to allow it to be done as a 2-LP set: "Cast albums don't sell." Yet over the years it has probably been one of the label's best sellers!
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
