Yes, Sony included that as a bonus track on the latest reissue. (There were rumours that all of L. Kert's tracks would be on as bonus tracks but in the end we just got the one.)
The main problem is that COMPANY was recorded with cast and orchestra in one studio. When Kert came in to overdub Dean Jones' vocals, you can still hear Jones faintly in the background. Kert has a more melodic voice, but Jones brings more edge to the performance.
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
