Only the opening section of the Overture is heard on the recording. Within that brief section, some of the lyrics are changed, so that only "la" is sung by all the members of the quintet. In the show, one member of the quintet sings the actual lyrics to the song ("Remember?") while the others sing "la" in counterpoint.
The second CD issue includes "Night Waltz II," which was recorded at the cast-recording session in 1973 but was not included on the original LP issue or on the first CD issue. There is also a bonus track of the rewritten version of "The Glamorous Life" from the film version, taken from the film soundtrack
